Rook has been setting the application automatically on all
pools to rbd for CephBlockPools, rook-ceph-rgw for
CephObjectStores, mgr on the built-in .mgr pool,
and nfs on the built-in .nfs pool.
The legacy pool device_health_metrics is long gone
from Pacific which is no longer supported, so we can
remove special handling for that pool in the upgrade
guide and in the code.
The application setting is now available on the pool spec
although it is not expected to commonly need to override
the default applications set by Rook.
The application for CephFilesystem pools is now being
set to cephfs, where it was previously blank.
