- Single commit, PR follows conventions laid out by @Gouthamve in #5822
* main.go: struct field CpuFile should be CPUFile
* influx_inspect: loop equivalent to `for key := range...`
* adds comments to exported fields and consts
* fixes typo in `CHANGELOG.md`: text for #4702 now matches number
- Removed a lot of unused code
- Consolidated types
- Improved allocations for converting b1 shards
- Eliminated allocations when sorting cursors
- Eliminated allocations from removing NaN and Infinity values,
they are removed by the cursors now
- Separated out the stats from the conversion tracker

A case (#5606) was found where a lot of data unexpectedly disappeared from a database
following a TSM conversion.
The proximate cause was an inconsistency between the root Bolt DB bucket list
and the meta data in the "series" bucket of the same shard. There were apparently valid
series in Bolt DB buckets that were no longer referenced by the meta data
in the "series" bucket - so-called orphaned series; since the conversion
process only iterated across the series found in the meta data, the conversion process
caused the orphaned series to be removed from the converted shards. This resulted in the
unexpected removal of data from the TSM shards that had previously been accessible
(despite the meta data inconsistency) in the b1 shards.
The root cause of the meta data inconsistency in the case above was a failure, in versions prior
to v0.9.3 (actually 3348dab) to update the "series" bucket with series that had been created in
previous shards during the life of the same influxd process instance.
This fix is required to avoid data loss during TSM conversions for shards that were created with
versions of influx that did not include 3348dab (e.g. prior to v0.9.3).
