Since table_state is a view to a compaction group, it makes sense
to rename it as so.
With upcoming incremental repair, each replica::compaction_group
will be actually two compaction groups, so there will be two
views for each replica::compaction_group.

So it can be used in the next patch that will refactor
compaction_state out of class compaction_manager.
