[RFC 0/3] xfs: Add new xfs multi AG shrink tests

["Nirjhar Roy (IBM)" <nirjhar.roy.lists@gmail.com>]

This patch series adds several multi AG shrink tests based on the RFC[1].
Patch 1/3 adds more basic shrink functionality tests to the already existing
ones in xfs/163.
Patch 2 adds tests that checks whether the filesystem is consistent
after several xfs_growfs operations(filesystem growth/shrink).
Patch 3 adds a test that repeatedly shrinks and shuts down the filesystem, thus
checking the log recovery correctness during multi AG shrink operations.
Tested them with 4k blocksize(on x86_64 with 4k page size) and 4k+64k blocksize
(on ppc64le with page size 64k).
