I'll split out caching the state of event filter builder to follow-up JIRA issue, as it's not mandatory to finalize SPARK-29779. |

What changes were proposed in this pull request?
This patch is the part 3 of SPARK-29779 and addresses remaining functionality: integrate compaction into FsHistoryProvider. This patch also addresses documentation about new configuration. Please refer the description of PR #27085 to see overall rationalization of this patch.
Why are the changes needed?
One of major goal of SPARK-28594 is to prevent the event logs to become too huge, and SPARK-29779 achieves the goal. We've got another approach in prior, but the old approach required models in both KVStore and live entities to guarantee compatibility, while they're not designed to do so.
Does this PR introduce any user-facing change?
No
How was this patch tested?
Added UT. Manual test will follow once earlier parts are merged and this patch is rebased.
