e7959094f6 lib/storage: remove prioritizing of merging small parts over merging big parts, since it doesn't work as expected 
The prioritizing could lead to big merge starvation, which could end up in too big number of parts that must be merged into big parts.

Multiple big merges may be initiated after the migration from v1.39.0 or v1.39.1. It is OK - these merges should be finished soon,
which should return CPU and disk IO usage to normal levels.

The function is useful for building heatmaps in Grafana from too big number of buckets.

if `-denyQueriesOutsideRetention` command-line flag is set.

app/vmalert: support multiple notifier urls (#584) (#590) 
* app/vmalert: support multiple notifier urls (#584)

User now can set multiple notifier URLs in the same fashion
as for other vmutils (e.g. vmagent). The same is correct for
TLS setting for every configured URL. Alerts sending is done
in sequential way for respecting the specified URLs order.

* app/vmalert: add basicAuth support for notifier client (#585)

The change adds possibility to set basicAuth creds for notifier
client in the same fasion as for remote write/read and datasource.

vmselect: fix label_replace when mismatch (#579) 
As per documentation on `label_replace` function: "If the regular
expression doesn't match then the timeseries is returned unchanged".

Currently this behavior is not enforced, if a regexp on an existing
tag doesn't match then the tag value is copied as-is in the destination
tag. This fix first checks that the regular expression matches the
source tag before applying anything.

Given the current implementation, this fix also changes the behavior
of the **MetricsQL** `label_transform` function which does not
document this behavior at the moment.

7209d58fbd app/vmselect/netstorage: increase concurrency when processing small number of time series with big number of data points per each time series 
Previously VictoriaMetrics was processing up to 32 time series in a single goroutine.
This could be slow if each time series contains big number of data points (10M+ or more), since only a single CPU core could be loaded with work,
while other CPU cores were idle. Fix this by launching GOMAXPROCS workers for time series processing.

This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/572

vmalert-537: allow name duplication for rules within one group. (#559) 
Uniqueness of rule is now defined by combination of its name, expression and
labels. The hash of the combination is now used as rule ID and identifies rule within the group.

Set of rules from coreos/kube-prometheus was added for testing purposes to
verify compatibility. The check also showed that `vmalert` doesn't support
`query` template function that was mentioned as limitation in README.

* interface Rule now unites both recording and alerting rules;
* configuration parser was moved to separate package and now performs
more strict validation;
* new endpoint for listing all groups and rules in json format was added;
* evaluation interval may be set to every particular group;

* vmalert: uncomment tests

* vmalert: rm outdated TODO

vmalert: avoid sending resolves for pending alerts (#498) 
Before the change we were sending notifications to notifier
if following conditions are met:
* alert is in Fire state
* alert is in Inactive state

We were sending Inactive notifications to resolve alert ASAP. 
Unfortunately, we were sending resolves for Pending alerts that become
Inactive, which is wrong.

In this change we delete alert from the active list if
it was Pending and become Inactive. In this way we now
have Inactive alerts only if they were in state Fire before.
See test change for example.

vmalert: cleanup and restructure of code to improve maintainability (#471) 
The change introduces new entity `manager` which replaces
`watchdog`, decouples requestHandler and groups. Manager
supposed to control life cycle of groups, rules and
config reloads.

Groups export an ID method which returns a hash
from filename and group name. ID supposed to be unique
identifier across all loaded groups.

Some tests were added to improve coverage.

Bug with wrong annotation value if $value is used in
 templates after metrics being restored fixed.

Notifier interface was extended to accept context.

New set of metrics was introduced for config reload.

43c39dc36c vendor: use github.com/VictoriaMetrics/fasthttp instead of github.com/fasthttp/fasthttp 
The upstream fasthttp may contain issues like 996610f021 ,
plus a code that isn't used by VictoriaMetrics. So let's use a private copy under our control instead.

app/vmalert: initial remote-write support for alerts state persistence. (#442) 
* app/vmalert: initial remote-write support for alerts state persistence.

If `remotewrite.url` flag is set, vmalert will send alerts state  via remote-write protocol to remote storage. The sending is asynchronous to avoid blocking calls in rules evaluation loop.

* app/vmalert: merge with master

* app/vmalert: write both `instant` and `for` alerts timeseries states in remote storage.

b4afe562c1 lib/storage: postpone reading data from blocks during search 
This eliminates the need for storing block data into temporary files on a single-node VictoriaMetrics
during heavy queries, which touch big number of time series over long time ranges.

This improves single-node VM performance on heavy queries by up to 2x.

d0d258b314 app/vmselect: limit the default value for -search.maxConcurrentRequests, so it plays well on systems with more than 16 vCPUs 
A single heavy request can saturate all the available CPUs, so let's limit the number of concurrent requests to lower value.

46bfdbe6cf app/vmselect/promql: do not take into account the previous point before time window in square brackets for min_over_time, max_over_time, rollup_first and rollup_last functions 
This makes the behaviour for these functions similar to Prometheus when processing broken time series with irregular data points
like `gitlab_runner_jobs`. See https://gitlab.com/gitlab-org/gitlab-exporter/issues/50 for details.

164278151f app/vmselect/promql: add aggr_over_time(("aggr_func1", "aggr_func2", ...), m[d]) function 
This function can be used for simultaneous calculating of multiple `aggr_func*` functions
that accept range vector. For example, `aggr_over_time(("min_over_time", "max_over_time"), m[d])`
would calculate `min_over_time` and `max_over_time` for `m[d]`.
