vmalert: add flag for disabling long-lived connections (keepalive) (#2395) 
The new flag `datasource.disableKeepAlive` allows disabling keepalive
connections. This may be useful if there are multiple datasource
replicas (e.g. vmselects) behind the HTTP balancer to avoid uneven
load spread because of long-lived connections.

If a vmstorage is reachable and returns an application-level error to vmselect,
then such error must be returned to the caller even if partial responses are allowed,
since it usually means cluster mis-configuration.

Partial responses may be returned only if some vmstorage nodes are temporarily unavailable.

Consul SD - update services on the watcher's start (#2202) 
* lib/discovery/consul: update services on the watcher's start

Previously, watcher's start was only initing goroutines for discovery
but not waiting for the first iteration to end. It means first Consul
discovery wasn't returning discovered targets until the next iteration.

The change makes the watcher's start blocking until we get first discovery
iteration done and all registries updated.

lib/index: reduce read/write load after indexDB rotation (#2177) 
* lib/index: reduce read/write load after indexDB rotation

IndexDB in VM is responsible for storing TSID - ID's used for identifying
time series. The index is stored on disk and used by both ingestion and read path.

IndexDB is stored separately to data parts and is global for all stored data.
It can't be deleted partially as VM deletes data parts. Instead, indexDB is
rotated once in `retention` interval.

The rotation procedure means that `current` indexDB becomes `previous`,
and new freshly created indexDB struct becomes `current`. So in any time,
VM holds indexDB for current and previous retention periods.
When time series is ingested or queried, VM checks if its TSID is present
in `current` indexDB. If it is missing, it checks the `previous` indexDB.
If TSID was found, it gets copied to the `current` indexDB. In this way
`current` indexDB stores only series which were active during the retention
period.

To improve indexDB lookups, VM uses a cache layer called `tsidCache`. Both
write and read path consult `tsidCache` and on miss the relad lookup happens.

When rotation happens, VM resets the `tsidCache`. This is needed for ingestion
path to trigger `current` indexDB re-population. Since index re-population
requires additional resources, every index rotation event may cause some extra
load on CPU and disk. While it may be unnoticeable for most of the cases,
for systems with very high number of unique series each rotation may lead
to performance degradation for some period of time.

This PR makes an attempt to smooth out resource usage after the rotation.
The changes are following:
1. `tsidCache` is no longer reset after the rotation;
2. Instead, each entry in `tsidCache` gains a notion of indexDB to which
they belong;
3. On ingestion path after the rotation we check if requested TSID was
found in `tsidCache`. Then we have 3 branches:
3.1 Fast path. It was found, and belongs to the `current` indexDB. Return TSID.
3.2 Slow path. It wasn't found, so we generate it from scratch,
add to `current` indexDB, add it to `tsidCache`.
3.3 Smooth path. It was found but does not belong to the `current` indexDB.
In this case, we add it to the `current` indexDB with some probability.
The probability is based on time passed since the last rotation with some threshold.
The more time has passed since rotation the higher is chance to re-populate `current` indexDB.
The default re-population interval in this PR is set to `1h`, during which entries from
`previous` index supposed to slowly re-populate `current` index.

The new metric `vm_timeseries_repopulated_total` was added to identify how many TSIDs
were moved from `previous` indexDB to the `current` indexDB. This metric supposed to
grow only during the first `1h` after the last rotation.

vendor: update github.com/VictoriaMetrics/metricsql from v0.37.0 to v0.38.0 
This adds more optimization cases for https://utcc.utoronto.ca/~cks/space/blog/sysadmin/PrometheusLabelNonOptimization

For example:

* Multi-level transform functions. For example, abs(round(foo{a="b"})) + bar{x="y"}
  is now optimized to abs(round(foo{a="b",x="y"})) + bar{a="b",x="y"}
* Binary operations with `on()`, `without()`, `group_left()` and `group_right()` modifiers.
  For example, foo{a="b"} on (a) + bar is now optimized to foo{a="b"} on (a) + bar{a="b"}
* Multi-level binary operations. For example, foo{a="b"} + bar{x="y"} + baz{z="q"}
  is now optimized to foo{a="b",x="y",z="q"} + bar{a="b",x="y",z="q"} + baz{a="b",x="y",z="q"}
* Aggregate functions. For example, sum(foo{a="b"}) by (c) + bar{c="d"}
  is now optimized to sum(foo{a="b",c="d"}) by (c) + bar{c="d"}

app/vmselect/promql: add support for @ modifier 
Add support for `@` modifier in MetricsQL according to https://prometheus.io/docs/prometheus/latest/querying/basics/#modifier

Extend the support with the following features:
* Allow using `@` modifier everywhere in the query. For example, `sum(foo) @ end()`
* Allow using arbitrary expression as `@` modifier. For example, `foo @ (end() - 1h)`
  returns `foo` value at `end - 1 hour` timestamp on the selected time range `[start ... end]`

It is expected that the de-duplication is applied during importing the exported data.

The deduplication is applied only when exporting data via /api/v1/export if `reduce_mem_usage=1` query arg isn't passed to the request.
