Add regression test for ATTACH PARTITION

Browse Source 
This test case uses a SQL function as partitioning operator, whose
evaluation results in the table's relcache being rebuilt partway
through the execution of an ATTACH PARTITION command.

It is extracted from 39808e8, which fixed a bug where this test case
failed on master and REL_11_STABLE, but passed on REL_10_STABLE.  The
partitioning code has changed a lot during v11 development, so this
makes sure that any patch applied to REL_10_STABLE fixing a
partition-related bug does not break it again.
