lib/auth: add NewTokenPossibleMultitenant() for parsing auth token, which can be multitenant
Disallow parsing multitenant token at auth.NewToken().

Use auth.NewTokenPossibleMultitenant() at vminsert only. All the other callers should call auth.NewToken(),
since they do not support multitenant token.

This is a follow-up for f0c06b428e

app/vmselect: follow-up after f0c06b428e
Remove extra error message when auth token is nil. The default message
about unsupported path should be more clear to the user who mistakenly
requested /multitenant path.

Add vmstorageUserTimeout flags to configure TCP user timeout (Linux) (#4423)
`TCP_USER_TIMEOUT` (since Linux 2.6.37) specifies the maximum amount of
time that transmitted data may remain unacknowledged before TCP will
forcibly close the connection and return `ETIMEDOUT` to the application.

Setting a low TCP user timeout allows RPC connections quickly reroute
around unavailable storage nodes during network interruptions.

app/vmselect/promql: add the ability to copy all the labels from one side of group_left()/group_right() operation
This is performed by specifying `*` inside group_left()/group_right().
Also allow specifying prefix for the copied labels via `group_left(...) prefix "..."` and `group_right(...) prefix "..."` syntax.
For example, the following query adds all the namespace-related labels to pod info, and prefixes all the copied label names with "ns_" prefix:

  kube_pod_info * on(namespace) group_left(*) prefix "ns_" kube_namespace_labels

This resolves the following StackOverflow questions:

app/vmselect/promql: recommend to use (a op b) keep_metric_names instead of a op b keep_metric_names
The `a op b keep_metric_names` is ambigouos to `a op (b keep_metric_names)` when `b` is a transform or rollup function.
For example, `a + rate(b) keep_metric_names`. So it is better to use more clear syntax: `(a op b) keep_metric_names`

all: add support for or filters in series selectors
This commit adds ability to select series matching distinct filters via a single series selector.
For example, the following selector selects series with either {env="prod",job="a"}
or {env="dev",job="b"} labels:

  {env="prod",job="a" or env="dev",job="b"}

The `or` filter is supported in all the VictoriaMetrics tools now.

app/vmselect/netstorage: follow-up after 173ccf4333
- Clarify docs about -replicationFactor command-line flag at vmselect
- Clarify description for -replicationFactor and -search.skipSlowReplicas command-line flags
- Fix the logic for returning responses if -search.skipSlowReplicas command-line flag
  is enabled. The logic was broken in the 173ccf4333,
  so it could return responses only if some of vmstorage nodes return error,
  while it should return when query results are successfully collected from more than
  (len(storageNodes) - replicationFactor) vmstorage nodes.

vmselect: introduce search.skipSlowReplicas cmd-line flag (#4538)
* vmselect: introduce `search.skipSlowReplicas` cmd-line flag

vmselect has two logical conditions during request processing when
`-replicationFactor` cmd-line flag is set:
1. If at least `len(storageNodes) - replicationFactor` responded, it could skip
waiting for the rest of nodes to respond. This could lead to problems described
here https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1207.
2. Mark response as partial if less than `len(storageNodes) - replicationFactor` responded
without an error.

The P1 showed itself error-prone and became the main reason why
`-replicationFactor` wasn't recommended to use at vmselect level.
However, this optimization could be still very useful in situations
when there are slow and fast replicas in cluster.

But P2 remains viable and important conditionless.
Hiding P1 behind the feature-flag `search.skipSlowReplicas`
should make `-replicationFactor` flag usable again. And let users
choose whether they want P1 to be respected.

vmselect: exit early from queue on context cancel (#4223)
* vmselect: exit early from queue on context cancel

When `-search.maxConcurrentRequests` is reached, vmselect puts
request in the queue. It is expected, that requests in the queue
will be processed as soon as it would be enough capacity to do so.

However, it could happen that while request was waiting its turn,
the client could have already cancel it (close the connection,
or just close the tab with UI). In this case, we should de-queue
such requests to avoid spending extra resources on them.

lib/fs: replace MkdirAllIfNotExist->MustMkdirIfNotExist and MkdirAllFailIfExist->MustMkdirFailIfExist
Callers of these functions log the returned error and then exit. The returned error already contains the path
to directory, which was failed to be created. So let's just log the error together with the call stack
inside these functions. This leaves the debuggability of the returned error at the same level
while allows simplifying the code at callers' side.

While at it, properly use MustMkdirFailIfExist instead of MustMkdirIfNotExist inside inmemoryPart.MustStoreToDisk().
It is expected that the inmemoryPart.MustStoreToDick() must fail if there is already a directory under the given path.

fix le buckets when adjacent vmrange is empty (#4021)
There is a bug here where if you have a single bucket like:

foo{vmrange="4.084e+02...4.642e+02"} 2 123

The expected output is three le encoded buckets like:

foo{le="4.084e+02"} 0 123
foo{le="4.642e+02"} 2 123
foo{le="+Inf"} 2 123

This correctly encodes the start and end of the vmrange.
If however, the input contains the previous bucket, and that bucket is
empty then you only get the end le and +Inf out currently, i.e:

foo{vmrange="7.743e+05...8.799e+05"} 5 123
foo{vmrange="6.813e+05...7.743e+05"} 0 123

results in:

foo{le="8.799e+05"} 5 123
foo{le="+Inf"} 5 123

This causes issues when you go to compute a quantile because this means
that the assumed lower bound of the buckets is 0 and this we interpolate
between 0->end rather than the vmrange start->end as expected.

app/vmselect: follow-up for 10ab086366
- Expose stats.seriesFetched at `/api/v1/query_range` responses too
  for the sake of consistency.

- Initialize QueryStats when it is needed and pass it to EvalConfig then.
  This guarantees that the QueryStats is properly collected when the query
  contains some subqueries.

app/vmselect: export seriesFetched stat for /query responses (#3925)
The change adds a new field `seriesFetched` to EvalConfig object.
Since EvalConfig object can be copied inside `Exec`,
`seriesFetched` is a pointer which can be updated by all copied
objects.

The reason for having stats is that other components, like vmalert,
could benefit from this information.

vmselect/netstorage: remove direct calls to Gosched to reduce amount of locks for global scope
using `runtime.Gosched` requires acquiring global lock to check if there are any other goroutines to perform tasks. with the latest versions of runtime it can pause running goroutines automatically without requiring to call `Gosched` directly.

app/vmselect/promql: use lock-less approach to gather results of parallel processing for evalRollup* funcs (#4004)
* vmselect/promql: refactor `evalRollupNoIncrementalAggregate` to use lock-less approach for parallel workers computation

Locking there is causing issues when running on highly multi-core system as it introduces lock contention during results merge.

New implementation uses lock less approach to store results per workerID and merges final result in the end, this is expected to significantly reduce lock contention and CPU usage for systems with high number of cores.

all: add Windows build for VictoriaMetrics
This commit changes background merge algorithm, so it becomes compatible with Windows file semantics.

The previous algorithm for background merge:

1. Merge source parts into a destination part inside tmp directory.
2. Create a file in txn directory with instructions on how to atomically
   swap source parts with the destination part.
3. Perform instructions from the file.
4. Delete the file with instructions.

This algorithm guarantees that either source parts or destination part
is visible in the partition after unclean shutdown at any step above,
since the remaining files with instructions is replayed on the next restart,
after that the remaining contents of the tmp directory is deleted.

Unfortunately this algorithm doesn't work under Windows because
it disallows removing and moving files, which are in use.

So the new algorithm for background merge has been implemented:

1. Merge source parts into a destination part inside the partition directory itself.
   E.g. now the partition directory may contain both complete and incomplete parts.
2. Atomically update the parts.json file with the new list of parts after the merge,
   e.g. remove the source parts from the list and add the destination part to the list
   before storing it to parts.json file.
3. Remove the source parts from disk when they are no longer used.

This algorithm guarantees that either source parts or destination part
is visible in the partition after unclean shutdown at any step above,
since incomplete partitions from step 1 or old source parts from step 3 are removed
on the next startup by inspecting parts.json file.

This algorithm should work under Windows, since it doesn't remove or move files in use.
This algorithm has also the following benefits:

- It should work better for NFS.
- It fits object storage semantics.

The new algorithm changes data storage format, so it is impossible to downgrade
to the previous versions of VictoriaMetrics after upgrading to this algorithm.

vmselect/promql: check for deadline in count_values fn (#3806)
* vmselect/promql: check for deadline in `count_values` fn

`count_values` could be very slow during the data processing.
Checking for deadline between iterations supposed to reduce
probability of exceeding `search.maxQueryDuration`.

The change also adds a new trace record, which captures the time
spent in aggregation function. Before that, the trace for aggr funcs
could be confusing since it doesn't account for all the places where
time was spent.

 * rollup_delta
 * rollup_deriv
 * rollup_increase
 * rollup_rate
 * rollup_scrape_interval

 If second argument is passed, then rollup function will return only the selected aggregation type.
 This change can be useful for situations where only one type of rollup calculation is needed.
 For example, `rollup_rate(requests_total[5m], "max")`.

app/vmselect/netstorage: reduce tail latency during query processing
Previously the selected time series were split evenly among available CPU cores
for further processing - e.g unpacking the data and applying the given rollup
function to the unpacked data.
Some time series could be processed slower than others.
This could result in uneven work distribution among available CPU cores,
e.g. some CPU cores could complete their work sooner than others.
This could slow down query execution.

The new algorithm allows stealing time series to process from other CPU cores
when all the local work is done. This should reduce the maximum time
needed for query execution (aka tail latency).

The new algorithm should also scale better on systems with many CPU cores,
since every CPU processes locally assigned time series without inter-CPU communications.

The inter-CPU communications are used only when all the local work is finished
and the pending work from other CPUs needs to be stealed.

lib/writeconcurrencylimiter: improve the logic behind -maxConcurrentInserts limit
Previously the -maxConcurrentInserts was limiting the number of established client connections,
which write data to VictoriaMetrics. Some of these connections could be idle.
Such connections do not consume big amounts of CPU and RAM, so there is a little sense in limiting
the number of such connections. So now the -maxConcurrentInserts command-line option
limits the number of concurrently executed insert requests, not including idle connections.

It is recommended removing -maxConcurrentInserts command-line option, since the default value
for this option should work good for most cases.

app/vmui: small usability improvements
- Show in the line tooltip the number of the query which generates the given line.
  This simplifies comparison of lines generated by multiple queries.

- Show metric name as __name__ label in the line tooltip in the same way as other labels are shown there.
  This makes the label information in the tooltip more consistent.

- Properly quote label values with JSON.stringify(). This prevents from improper formatting
  when label values contain doublequote chars.

- Remove double curly braces artifact at graph legend for lines without names and labels.

- Properly use modifier for regular expressions across the code.

app/vmselect/promql: do not extend too short lookbehind window for rate() function if it is set explicitly
Previously too short lookbehind window d for rate(m[d]) could be automatically extended
if it didn't cover at least two raw samples. This was needed in order to guarantee
non-empty results from rate(m[d]) on short time ranges.

Now the lookbehind window isn't extended if it is set explicitly,
since it is expected that the user knows what he is doing.

The lookbehind window continues to be extended when needed if it isn't set explicitly.
For example, in the case of rate(m).
