util: use go-ceph instead of "rados" command for GetPoolID()
GetPoolID() did not return ErrPoolNotFound in case the pool could not be found. This has been addressed as well, so that looking for an existing pool behaves the same for checking by Name or ID. Signed-off-by: Niels de Vos <ndevos@redhat.com>
