Stop using intersphinx

Remove intersphinx from the docs build as it triggers network calls that
occasionally fail, and we don't really use intersphinx (links other
sphinx documents out on the internet)

This also removes the requirement for internet access during docs build.

This can cause docs jobs to fail if the project errors out on
warnings.

Enumerate Projects with Unscoped Tokens

Creating a client with a session using an Unscoped tokens now sets auth
info in client.  This Auth Info is necessary in order to enumerate
projects.  This is the standard login path for Horizon.
