* deployment/docker/docker-compose-cluster.yml: bump VictoriaMetrics Cluster components to the latest v1.83.0 version
* deployment/docker/docker-compose.yml: bump VictoriaMetrics Single node and vmutils to the latest v1.83.0 version
Previously the `quotesEscape` function was escaping only double quotes.
This wasn't enough, since the input string could contain other special chars,
which must be escaped when put inside JSON string. For example, carriage return and line feed chars (\n\r),
backslash char, etc. This led to the following issues, which were improperly fixed:
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/890 - this issue
was "fixed" by introducing the `crlfEscape` function, which led to unnecessary
complications in user templates, while not fixing various corner cases
such as backslash chars in the input string.
See 1de15ad490
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3139 - this issue
was "fixed" by urlencoding the whole string passed to -external.alert.source
command-line flag. This led to invalid urls, which couldn't be parsed by Grafana.
See 00c838353d
and 4bd0244599
This commit properly encodes the input string passed to `quotesEscape`, so it can be safely embedded inside JSON strings.
This commit deprecates crlfEscape template function and adds the following new template functions:
- strvalue and stripDomain - these functions are supported by Prometheus, so they were added
for compatibility purposes.
- jsonEscape and htmlEscape for converting the input string to valid quoted JSON string
and for html-escaping the input string, so it could be safely embedded as a plaintext
into html.
This commit also documents all supported template functions at https://docs.victoriametrics.com/vmalert.html#template-functions
The deprecated crlfEscape function isn't documented on purpose, since its usefulness is negative in general case.
Cluster components always have `-cluster` suffix. The change fixes
incorrect image tag in docker-compose manifest.

* deployment/docker: move cluster compose env to master branch
The change supposed to simplify the process of maintaining for
single/cluster docker-compose envs, alerts, dashboards. It also
supposes to reduce confusion for users when looking for cluster
related alerts/configs.

The `-mod=vendor` is automatically set when there is a `vendor` directory
starting from Go1.14 - see https://go.dev/doc/go1.14#go-command
Since the minimum supported Go version for VictoriaMetrics is Go1.17,
then the `-mod=vendor` option is no longer needed.
* deployment/docker/Makefile: added docker-scan
docker-scan based on native 'docker scan' function that use snyk.io, see https://docs.docker.com/engine/scan/
* set to call 'docker-scan after release binaries but before publishing
The new metric `vmagent_remotewrite_queues` exports a static value of
number of configured remote write queus. This metric is useful to
calculate total saturation per each configured URL with given number
of queues. See corresponding changes to vmagent alerts and dashboard.

alerts: filter out non error log messages for `TooManyLogs`
Info and Warn error levels aren't always a result of malfunctioning
or faulty state. So we filter them out.
Lowering threshold from 50% to 5% will be more sufficient
for discovering un-healthy system state. It also goes in
sync with alert definition in cluster branch.
