all: consistently use 'any' instead of 'interface{}'
'any' type is supported starting from Go1.18. Let's consistently use it
instead of 'interface{}' type across the code base, since `any` is easier to read than 'interface{}'.

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.

app/vmselect/prometheus: ignore match[] additionally to extra_filters[] and extra_label if -search.ignoreExtraFiltersAtLabelsAPI command-line flag is set
The match[] at /api/v1/labels and /api/v1/label/.../values also may lead to slow requests and
high resource usage if it matches big number of time series. So it must be igrnored if -search.ignoreExtraFiltersAtLabelsAPI
command-line flag is set.

app/vmselect: add -search.maxLabelsAPIDuration and -search.maxLabelsAPISeries options for fine-tuning CPU and RAM usage for /api/v1/series , /api/v1/labels and /api/v1/label/.../values
This commit returns back limits for these endpoints, which have been removed at 5d66ee88bd ,
since it has been appeared that missing limits result in high CPU usage, while the introduced concurrency limiter
results in failed lightweight requests to these endpoints because of timeout when heavyweight requests are executed.

lib/storage: do not check the limit for -search.maxUniqueTimeseries when performing /api/v1/labels and /api/v1/label/.../values requests
This limit has little sense for these APIs, since:

- Thses APIs frequently result in scanning of all the time series on the given time range.
  For example, if extra_filters={datacenter="some_dc"} .

- Users expect these APIs shouldn't hit the -search.maxUniqueTimeseries limit,
  which is intended for limiting resource usage at /api/v1/query and /api/v1/query_range requests.

Also limit the concurrency for /api/v1/labels, /api/v1/label/.../values
and /api/v1/series requests in order to limit the maximum memory usage and CPU usage for these API.
This limit shouldn't affect typical use cases for these APIs:

- Grafana dashboard load when dashboard labels should be loaded
- Auto-suggestion list load when editing the query in Grafana or vmui

app/vmselect: do not limit concurrency for static and fast queries
Previously concurrency for static and fast queries was limited with the -search.maxConcurrentRequests
command-line flag. This could complicate identifying heavy queries via `vmui` at `Top queries` and `Active queries` pages,
since `vmui` and these pages couldn't be opened on overloaded vmselect.

Thanks to @f41gh7 for the idea.

* Add /prettify-query API handler

* Replace UI pretiffier using prettifier API

* Add showing server errors

Had to pass setQueryErrors from useFetchQuery.ts

* Use serverUrl from global AppState

* Change icon to AutoAwsome icon + added style change color when button is active

* Add sync/await to prettifyQuery function

* Doc public function for lint

* Minor async fix

* Removed extra blank lines

* Extract usePrettifyQuery hook

* Made more generic style for :active button

* Refactor usePrettifyQuery

However, prettify errors don't clean up query errors, but should

* Add prettyQuery functionality to CHANGELOG.md

* Reuse queryErrors

* Unhide errors on start

all: add support for or filters in series selectors
This commit adds ability to select series matching distinct filters via a single series selector.
For example, the following selector selects series with either {env="prod",job="a"}
or {env="dev",job="b"} labels:

  {env="prod",job="a" or env="dev",job="b"}

The `or` filter is supported in all the VictoriaMetrics tools now.

- Expose stats.seriesFetched at `/api/v1/query_range` responses too

- Initialize QueryStats when it is needed and pass it to EvalConfig then.
  This guarantees that the QueryStats is properly collected when the query

app/vmselect: export seriesFetched stat for /query responses ()
The change adds a new field `seriesFetched` to EvalConfig object.
Since EvalConfig object can be copied inside `Exec`,
`seriesFetched` is a pointer which can be updated by all copied
objects.

The reason for having stats is that other components, like vmalert,
could benefit from this information.
