[TESTING] rbd-group-snapshots use rbd.CloneImageByID()

The new rbd_clone4() API is only available in Squid and newer. Squid is
not yet released, therefor it is required to use the container image
from the Ceph CI registry.

rbd_clone() is added in PR ceph/go-ceph#1000, that branch needs to be
vendored as well.
