Use "keystone_public_api" as the backend name

And similarly for keystone-admin-api.

"keystone_public_api" is used instead of "keystone-public-api" as the
backend name in the haproxy configuration. Ideally, we should not rely
on names defined in the user configuration, but we have no solution for
this right now.
