* FEATURE: vmagent: add `/ready` HTTP endpoint, which returns 200 OK status code when all the service discovery has been initialized.
This may be useful during rolling upgrades. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/875
* BUGFIX: properly calculate `topk_*` and `bottomk_*` functions from [MetricsQL](https://victoriametrics.github.io/MetricsQL.html) for time series with gaps.
