Review Comment:
`isEligibleForCompaction` accepts the skipDBs SET, we should populate and
reuse it when checking the next candidates

> Currently a simple user can create a table with
> {color:#6a8759}no_auto_compaction=true{color} table property and create an
> aborted write transaction writing to this table. This way a malicious user
> can prevent cleaning up data for the aborted transaction, creating
> performance degradation.
> This configuration should be allowed to overridden on a database level:
> adding {color:#6a8759}no_auto_compaction=false{color} should override the
> table level setting forcing the initiator to schedule compaction for all
> tables.
