app/vmselect/prometheus: do not drop match[] filters if -search.ignoreExtraFiltersAtLabelsAPI flag is set

The `match[]` filter is mandatory at /api/v1/series, so it mustn't be dropped here.

There is no sense in dropping `match[]` filter together with `extra_label` and `extra_filters[]`
at /api/v1/labels and /api/v1/label/.../values if -search.ignoreExtraFiltersAtLabelsAPI commnad-line flag is set,
since:
- the `match[]` filter triggers slow path at these APIs;
- the `extra_label` and `extra_filters[]` filters narrow down the number of matched time series,
  so they improve performance comparing to the case when only `match[]` filter is left,
  while `extra_label` and `extra_filters[]` filters are dropped.

This is a follow-up for 0b7a23a91d

/api/v1/admin/tsdb/delete_series

Deletes time series from VictoriaMetrics

Note that handler accepts any HTTP method, so sending a GET request to /api/v1/admin/tsdb/delete_series will result in deletion of time series.

Single-node VictoriaMetrics:

curl -v http://localhost:8428/api/v1/admin/tsdb/delete_series -d 'match[]=vm_http_request_errors_total'

The expected output should return HTTP Status 204 and will look like:

*   Trying 127.0.0.1:8428...
* Connected to 127.0.0.1 (127.0.0.1) port 8428 (#0)

Cluster version of VictoriaMetrics:

curl -v http://<vmselect>:8481/delete/0/prometheus/api/v1/admin/tsdb/delete_series -d 'match[]=vm_http_request_errors_total'

Prometheus querying API usage
URL format for VictoriaMetrics cluster VictoriaMetrics accepts limit query arg for /api/v1/series handlers for limiting the number of returned entries. For example, the query to /api/v1/series?limit=5 returns a sample of up to 5 series, while ignoring the rest. If the provided limit value exceeds the corresponding -search.maxSeries command-line flag values, then limits specified in the command-line flags are used.
