[~ekoifman] [~steveyeom2017] should it be? Alter table concatenate that preserves txn boundaries (i.e. concats files in each directory separately) would generally be pointless, and destroying txn boundaries to combine directories is basically a compaction and should be done by compactor, as far as I understand

> ALTER TABLE CONCATENATE is not supported on Micro-managed table. 
> Example qtest is "alter_merge_2_orc.q" and the unsupportability is revealed when we start with tables in micro-managed table type(insert_only transactional).
