Pete Zaitcev 35e07e2982 Permit functional tests against Swift with Keystone
While poking at such problems with authentication other than swauth
it was useful to allow stock functional tests running back-to-back
at two clusters, with tempauth and Keystone.

When running the legacy tests, this version packs account into user
the way it was down previously. This way we do not need to repack
them before every call to get_auth. The downside is additional work
to be done when setting ACLs.
