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]

1a01fe2cf2 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.
