Hi!

Just noticed by a failing tempest.api.compute.test_versions.TestVersions.test_get_version_details test:
The versions answer of the components always return the listen address of the corresponding daemon. 
Is this the intended behavior? I think it should tell the public endpoint, the listening address in a HA cluster
cannot nor should be reached from the outside.

E.g. we have a  setup, where every service have an apache proxy in front of it, so getting the versions returns:

# curl http://192.168.168.100:8774 

{"versions": [{"status": "SUPPORTED", "updated": "2011-01-21T11:33:21Z", "links": [{"href": "http://127.0.0.1:8774/v2/", "rel": "self"}], "min_version": "", "version": "", "id": "v2.0"}, {"status": "CURRENT", "updated": "2013-07-23T11:33:21Z", "links": [{"href": "http://127.0.0.1:8774/v2.1/", "rel": "self"}], "min_version": "2.1", "version": "2.12", "id": "v2.1"}]}

Notice the href: "http://127.0.0.1:8774/xxx" answer.

Or the reason is to not return the public endpoint that it would require a keystone session, and the versions API must be lightweight?
