Ceph

It would be convenient for test purposes to have

ceph_objectstore_tool OBJECT remove

to be the equivalent of

for pgid in $(./ceph_objectstore_tool --data-path dev/osd0 --journal-path dev/osd0.journal --op list-pgs) ; do object=$(./ceph_objectstore_tool --data-path dev/osd0 --journal-path dev/osd0.journal --pgid $pgid --op list | grep '"oid":"GROUP"') ; test -n "$object" && break ; done ; ./ceph_objectstore_tool --data-path dev/osd0 --journal-path dev/osd0.journal --pgid $pgid "$object" remove 

it would fail if more than one object is found by the same name.
