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
