96ff8d9adb 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.

20812008a7 lib/storage: remove metricID with missing metricID->metricName entry
The metricID->metricName entry can be missing in the indexdb after unclean shutdown
when only a part of entries for new time series is written into indexdb.

Recover from such a situation by removing the broken metricID. New metricID
will be automatically created for time series with the given metricName
when new data point will arive to it.

1575a560f0 app/vmselect/netstorage: adaptively adjust the maximum inmemory file size for storing temporary blocks
The maximum inmemory file size now depends on `-memory.allowedPercent`.
This should improve performance and reduce the number of filesystem calls
on machines with big amounts of RAM when performing heavy queries
over big number of samples and time series.
