> Guard all writes to metadata table even for tables where locking is not enabled.
> As of now, we guard all writes to metadata table by taking a data table lock. This might work well for tables where multi-writer is enabled and so locking does take place. but for tables where multi-writer is not enabled, changes to metadata table happens w/o any lock. 
> so, if async compaction is running, it could potentially overstep w/ just 1 writer. both could concurrently try to update metadata table.
