* app/vmagent: allow vm proto for kafka consumer and producer
it should reduce network usage up to 50%.
According to benchmarks without any encoding at kafka topic, it reduces traffic up to 50%.
With enabled zstd at kafka topic, it shows no diffence in traffic. So it
doesn't make much sense to use it.

Previously the -maxConcurrentInserts was limiting the number of established client connections,
which write data to VictoriaMetrics. Some of these connections could be idle.
Such connections do not consume big amounts of CPU and RAM, so there is a little sense in limiting
the number of such connections. So now the -maxConcurrentInserts command-line option
limits the number of concurrently executed insert requests, not including idle connections.
It is recommended removing -maxConcurrentInserts command-line option, since the default value
for this option should work good for most cases.
Alert `RequestErrorsToAPI` could be permanently triggered due to
mistakes in clients configuration. However, such requests are unlikely
to cause VM health state change. So there is no need in displaying
this alert because there will be no correlation caused by it.

The new panels have been added to the vmstorage and drilldown rows.
`Disk space usage %` is supposed to show disk space usage percentage.
This panel is now also referred by `DiskRunsOutOfSpace` alerting rule.
This panel has Drilldown option to show absolute values.
`Disk space usage % by type` shows the relation between datapoints
and indexdb size. It supposed to help identify cases when indexdb
starts to take too much disk space.
This panel has Drilldown option to show absolute values.

The change list is the following:
* bump Grafana version to 9.2.6;
* replace old "Graph" panel with "TimeSeries" panel;
* show % usage of Mem and CPU additionally to of absolute values;
* `Caches` row was removed. All needed info for caches is now part of `Troubleshooting`;
* add Annotations for Alert triggers. Not all alerts are supposed to be displayed
on the dashboard, but only those with label `show_at: dashboard`.
See `alerts.yml` change.

The purpose of the update is to make the dash more usable
for large installations with many instances. Panels which showed
metrics per-instance (Mem, CPU) now are showing metrics per-job or min/max/avg
aggregations in % instead. This supposed to help immediately to identify
resource shortage and remain usable for small and big installations.
For cases when detailed info is needed, to the bottom of the dashboard
a new row `Drilldown` was added. Panels like Mem or CPU now contain
a `data-link` named `Drilldown` (cis shown on line click) which takes
user to more detailed panel.
The change list is the following:
* bump Grafana version to 9.1.0;
* replace old "Graph" panel with "TimeSeries" panel;
* improve Uptime panel to show number of instances per job;
* show % usage of Mem and CPU instead of absolute values;
* `Caches` row was removed. All needed info for caches is now part of `Troubleshooting`;
* add `Drilldown` section for detailed resource usage;
* add Annotations for Alert triggers. Not all alerts are supposed to be displayed
on the dashboard, but only those with label `show_at: dashboard`.

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.

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.

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.
