app/vmselect: add ability to pass match[], start and end to /api/v1/labels
...
This makes the `/api/v1/labels` handler consistent with already existing functionality for `/api/v1/label/.../values`.
See https://github.com/prometheus/prometheus/issues/6178 for more details.

app/vmselect: adjust end arg instead of adjusting start arg if start > end
...
`start` arg has higher chances to be set properly comparing to `end` arg,
so it is expected that the `end` arg could be adjusted if it was set incorrectly.

app/vmselect/prometheus: add -search.maxLookback command-line flag for overriding dynamic calculations for max lookback interval
...
This flag is similar to `-search.lookback-delta` if set. The max lookback interval is determined dynamically
from interval between datapoints for each input time series if the flag isn't set.
The interval can be overriden on per-query basis by passing `max_lookback=<duration>` query arg to `/api/v1/query` and `/api/v1/query_range`.
