Revert change I2f8ae86e17d26ec4defa16e843faa8987d27fac9

The commit breaks creation of user rc file.
Now devstack doesn't create certificate for user
(because it's too early to do it) and doesn't react
to changes of EC2/S3 urls if they is recreated by devstack plugins.
So the commit totally broke ec2-api gating for example.
