This reverts commit 4c05e5f966.
Moving cleanup to maintenance group made its operation time up to
10x slower than previous release. It's a blocker to 4.6 release,
so let's revert it until we figure this all out.
Probably this happens because maintenance group is fixed at a
relatively small constant, and cleanup may be incrementally
generating backlog for regular compaction, where the former is
fighting for resources against the latter.
Fixes#10060.
