Clean up URI handling

The two functions auth_uri_transform() and identity_uri_transform()
implicitly assume that the identity endpoint has no path component other
than 'v2.0'. This blocks modern deployment designs, so drop these
functions.

Probably will need some dependencies to clean up consumers of these
functions.
