List contains examples for the alerting rules which might be executed
via `vmalert` to track the health state of VM components. It is assumed
that list will be revised and calibrated for each system individually.
On templates validation stage vmalert does not acutally send queries, so for complex
chained expression validation may fail. To avoid this, we add a blank sample in response
so validation can pass successfully. Later, during the rule execution, stub will be replaced
with real `query` function.

Currently, alertmanager spams logs with `Notify attempt failed, will retry later` message
because default receiver is unreachable. The change updates default configuration with
blackhole receiver which means alertmanager will continue to accept alerts but won't make
attempts to send them anywhere.

Previously it could be modified in order to improve response cache hit ratio.
This is unneeded, since cache hit ratio should remain good because the query time range
should be already aligned to multiple of `step` values.
See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/976
* Adds query stat handler,
for query and query_range api, victoriametrics tracks query execution time,
stats are expored at /api/v1/status/queries endpoint with topN param

Previously such parts could remain undeleted for long durations until they are merged with other parts.
This should help for `-retentionPeriod` values smaller than one month.
