Meta queries (SHOW TAG VALUES, SHOW TAG KEYS, SHOW SERIES CARDINALITY, etc.) do not respect
the QueryTimeout config parameter. Meta queries should check the query context when possible
to allow cancellation and timeout. This will not be as frequent as regular queries, which
use iterators, because meta queries return data in batches.
Add a context.Context to
(*Store).MeasurementNames()
(*Store).MeasurementsCardinality()
(*Store).SeriesCardinality()
(*Store).TagValues()
(*Store).TagKeys()
(*Store).SeriesSketches()
(*Store).MeasurementsSketches()
which is tested for timeout or cancellation
to allow limitation of time spent in meta queries
