9afd19d375 app/vmalert: add retries to remotewrite (#605)
* app/vmalert: add retries to remotewrite

Remotewrite pkg now does limited number of retries if write request failed.
This suppose to make vmalert state persisting more reliable.

New metrics were added to remotewrite in order to track rows/bytes sent/dropped.

defaultFlushInterval was increased from 1s to 5s for sanity reasons.

ee03b4ccbd lib/promscrape: prevent from too big deadline misses on scrape retries
The maximum deadline miss duration is reduced to 2x scrape_interval in the worst case.
By default it is limited to scrape_interval configured for the given scrape target.

156c83d112 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.

a586b8b6d4 app/vminsert/netstorage: do not re-route every time series to more than two vmstorage nodes when certain vmstorage nodes are temporarily slower than the rest of them
Previously vminsert may spread data for a single time series across all the available vmstorage nodes
when vmstorage nodes couldn't handle the given ingestion rate. This could lead to increased usage
of CPU and memory on every vmstorage node, since every vmstorage node had to register all the time
series seen in the cluster. Now a time series may spread to maximum two vmstorage nodes under heavy load.
Every time series is routed to a single vmstorage node under normal load.

46c5c0772c 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.

ea2ed4b7e8 vmalert: add support for TLS configuration (#578)
app/vmalert: add support for TLS configuration

Add support for TLS optional configuration in a similar fashion to what
is currently supported in other vmutils such as vmagent. TLS
configuration options are distinct for datasource, remoteRead,
remoteWrite as well as notifier.

0fdbe5de25 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

3a444bb7bb lib/promrelabel: add support for keep_if_equal and drop_if_equal actions to relabel configs
These actions may be useful for filtering out unneeded targets and/or metrics if they contain equal label values.
For example, the following rule would leave the target only if __meta_kubernetes_annotation_prometheus_io_port
equals __meta_kubernetes_pod_container_port_number:

  - action: keep_if_equal
    source_labels: [__meta_kubernetes_annotation_prometheus_io_port, __meta_kubernetes_pod_container_port_number]
