Keystone: Remove unnecessary binds for admin endpoint

In the past Keystone required a separate instance for admin endpoint.
However that requirement was removed and current TripleO deploys only
a single keystone instance, which listens on tcp/5000 in
KeystonePublicApiNetwork [1].

Now haproxy forwards all keystone api access to tcp/5000 in
KeystonePublicApiNetwork and no longer uses backend on tcp/35357 in
KeystoneAdminApiNetwork.
