Each extension instance can create multiple clients. Moving the logic to extension start is better aligned with the extension lifecycle and prevent potential collisions, all clients will share the same compaction folder already cleaned up.

Description:
This PR includes a new flag cleanup_on_start for the compaction section.
During compaction a copy of the database is created, when the process is unexpectedly terminated that temporary file is not removed. That could lead to disk exhaustion given the following scenario:
This mitigates the potential risk of those temporary files left in a short period of time, by this scenario or similar ones.
Testing:
Included corner case where two instances of the extensions are spawned and one is compacting while the other would attempt to cleanup.
Documentation:
Included description in the README of the new configuration flag
