> As part of HIVE-6405's attempt to make HCatalog and Hive behave in similar ways with
regards to immutable tables, this is a companion task to introduce the notion of an immutable
table, wherein all tables are not immutable by default, and have this be a table property.
If this property is set for a table, and we attempt to write to a table that already has data
(or a partition), disallow "INSERT INTO" into it from hive(if destination directory is non-empty).
This property being set will allow hive to mimic HCatalog's current immutable-table property.
