Make database backups work with openstack Train

This PS fixes a problem with the main backup script in the helm-toolkit,
which tries to create a swift container using the SWIFT_URL. The problem
is that the SWIFT_URL is malformed because the call to openstack get
catalog list has a different format in Train than it did in Stein. So a
solution that works for both Train and Stein is needed. This patch will
use openstack catalog show instead and will extract the public URL from
that output.
