d5dddb0953 all: use %w instead of %s for wrapping errors in fmt.Errorf
This will simplify examining the returned errors such as httpserver.ErrorWithStatusCode .
See https://blog.golang.org/go1.13-errors for details.

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.

deployment/docker: replace Prometheus with vmagent (#589)
vmagent replaces Prometheus to perform scrapes and writes
into VictoriaMetrics installation. Prometheus datasource was
dropped, but its config was reused to feed vmagent.

Change also contains simplification in dashboard propagation
to Grafana container by removing excessive json manipulation
steps.

app/vmalert: move flags description and initialization into subpackages
The change adds no new functionality and aims to move flags definitions
to subpackages that are using them. This should improve readability
of the main function.

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: 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.

2a39ba639d 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]

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.
