(cherry picked from commit 0854032)

Fixes apache#9962

Motivation

Offloaded ledgers can be orphaned on topic deletion.

This is a redo of apache#15914 which conflicted with concurrently merged apache#17736 thus resulting in apache#17889 .

apache#17736 made a decision to not allow managed ledger trimming for the fenced mledgers because in many case fencing indicates a problems that should stop all operations on mledger. At the same time fencing is used before deletion starts, so trimming added to the deletion process cannot proceed.
After discussion with @eolivelli I introduced new state, FencedForDeletion, which acts as Fenced state except for the trimming/deletion purposes.

Modifications
