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.

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.

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

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

- action: keep_if_equal
source_labels: [__meta_kubernetes_annotation_prometheus_io_port, __meta_kubernetes_pod_container_port_number]

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

`query` template function that was mentioned as limitation in README.
