Fallback to root endpoint (when negotiating an API version) does not work

[Dmitry Tantsur]

Currently this code patch can be hit by doing:

 $ openstack --debug baremetal node list --os-baremetal-api-version 1

The error response does not contain the version header (which is probably a bug on its own), so ironicclient tries to fetch /v1, but fails with:

 EndpointNotFound: Could not find requested endpoint in Service Catalog.

This is because SessionClient._make_simple_request does not provide enough information to Session about the required catalog endpoint.

    Pass missing arguments to session in SessionClient._make_session_request

    If a server does not return API version headers, this will make the fallback
    to /v1 work correctly.
