[ocata] novaclient .client.Client parameters have changed and auth fails as a result

[Jason Hobbs]

I get this error when running the run-tempest action. This only happens when testing against ocata. This is from cs:~openstack-charmers-next/xenial/tempest

Here is the full log:

Here's a bigger log of the failure:

I think this is caused by changes in python-novaclient in ocata.

If you look at the release notes (https://docs.openstack.org/releasenotes/python-novaclient/ocata.html), the positional args accepted for novaclient.client.Client are:

version, username, api_key, project_id, auth_url

This is different than previous versions, where project_id was actually tenant/project name, not the tenant/project id.

    Fix novaclient creation for ocata and later.

    novaclient.client.Client's positional args changed in 7.0.0 (ocata),
    breaking this charm. This commit changes the client to use
    keystoneauth1 based session authentication to work around that issue.

    Also enable ocata tests.
