Don't check for existing endpoints

We really should only have code that create endpoints once, making all
osc calls get_or_set adds 3 seconds per call for no really good
reason.

This also stops creating the internal endpoints in the service
catalog. It's a pattern that we're trying not to propogate, so lets
not have it in devstack any more.
