vmalert: support rules backfilling (aka replay) (#1358)
* vmalert: support rules backfilling (aka `replay`)

vmalert can `replay` configured rules in the past
and backfill results via remote write protocol.
It supports MetricsQL/PromQL storage as data source,
and can backfill data to remote write compatible
storage.

Supports recording and alerting rules `replay`. See more
details in README.
