We are moving the necessary code for 2.0 from the influxdb 1.X
repository to the platform 2.0 repository. The logger is an unnecessary
dependency on the old influxdb that is making life more complicated.
This commit fixes an issue with the series file compaction
process where tombstones are lost after compaction and series
existence checks are not correct. This commit also fixes some
smaller flushing issues within the series file that mainly
related to testing.
