Review comment:
As for some tables where SCM does not need to have cache, so that is the
reason for introducing CacheType.
And also for some tables like deletedtable, where this is used by background
thread inOM, these does not need cache.
And as for volume/bucket table we plan to have entire table info, and
cleanup for them is no-op, even after flush to db, where as for partial cache
the cache entries will be cleaned up. This is the only difference between full
table cache vs partial table cache.
