MCOL-4769 Fix cache bugs. (#2151)

Browse Source 
* MCOL-4769 Do not replay INSERTs and LDIs on the replica nodes when
the write cache is enabled.

* MCOL-4769 If a table is created with the write cache disabled
(i.e. when columnstore_cache_inserts=OFF), make it accessible when
the cache feature is enabled (columnstore_cache_inserts=ON).
