3a444bb7bb lib/promrelabel: add support for keep_if_equal and drop_if_equal actions to relabel configs
These actions may be useful for filtering out unneeded targets and/or metrics if they contain equal label values.
For example, the following rule would leave the target only if __meta_kubernetes_annotation_prometheus_io_port
equals __meta_kubernetes_pod_container_port_number:

  - action: keep_if_equal
    source_labels: [__meta_kubernetes_annotation_prometheus_io_port, __meta_kubernetes_pod_container_port_number]

b0131c79b6 lib/storage: improve search speed for time series matching Graphite whildcards such as foo.*.bar.baz
Add index for reverse Graphite-like metric names with dots. Use this index during search for filters
like `__name__=~"foo\\.[^.]*\\.bar\\.baz"` which end with non-empty suffix with dots, i.e. `.bar.baz` in this case.

This change may "hide" historical time series during queries. The workaround is to add `[.]*` to the end of regexp label filter,
i.e. "foo\\.[^.]*\\.bar\\.baz" should be substituted with "foo\\.[^.]*\\.bar\\.baz[.]*".

b6d88bac04 vendor: use github.com/VictoriaMetrics/fasthttp instead of github.com/fasthttp/fasthttp
The upstream fasthttp may contain issues like 996610f021 ,
plus a code that isn't used by VictoriaMetrics. So let's use a private copy under our control instead.

Newly added index entries can be missing after unclean shutdown, since they didn't flush to persistent storage yet.
Log about this and delete the corresponding metricID, so it could be re-created next time.

with the previous protocol. So it is required that both vminsert and vmstorage nodes are updated.

bf1869d33d lib/promscrape: allow overriding external_labels as Prometheus does
Prometheus docs at https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config say:

> In communication with external systems, they are always applied only
> when a time series does not have a given label yet and are ignored otherwise.

Though this may result in consistency chaos when scrape targets override `external_labels`,
let's stick with Prometheus behavior for the sake of backwards compatibility.

There is last resort in vmagent with `-remoteWrite.label`, which consistently
sets the configured labels to all the metrics before sending them to remote storage.
