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.

Display stack owner info on stack-list

When listing stacks using the --global-tenant flag, the user is not able
to tell who each stack belongs to.  Furthermore, the problem may also
happen if there are multiple users within the same project.

This adds a --show-owner flag to stack-list to display the stack_owner
information when doing a normal stack list.  This flag is also set to
true when using --global-tenant, including an extra project field as
well, since the username is not unique across all projects.
