* All metadata for each shard is now stored in a single key with compressed value
* Creation of new metadata no longer requires a syncrhnous write to Bolt. It is passed to the WAL and written to Bolt periodically outside the write path
* Added DeleteSeries to WAL and updated bz1 to remove series there when DeleteSeries or DropMeasurement are called
This commit fixes the b1 cursor so that reads from either the cache
or bolt buffer will check against the previously read key to ensure
that two of the same keys are not returned.
Fixes#3571.
This commit fixes issues found from using a more complex `testing/quick`
implementation of the `WriteIndex()` test. The newer test inserts
multiple sets of random data that's confined to a smaller random space
so there's more chance of overlapping data.
The fixes were primarily around inserting old data or inserting the same
timestamp multiple times for a single write. The block splitting was not
working correctly before and the sorting and deduping was not handled
correctly.
