k0: move registry to ceph-waw3

ceph-waw2 has currently some production issues [1] which have started to
cause write failures in the registry. The registry is the only user of
ceph-waw2's affected pool, so we reduce the dumpster fire blast radious
by moving it over to ceph-waw3.

This has already been deployed and data has been migrated over (via
s3cmd sync), and the migration has been verified (by a push and pull,
and pull of an older image).

[1] - pgs stuck inactive in the object storage pool
