fuel-octane uses the deprecated keystone command line client instead of openstack

[Ilya Kharin]

The upgrade-env command uses the deprecate keystone client instead of the openstack client to obtain the id of the service tenant.

Steps to reproduce:
1. Upgrade the master node to 9.0
2. Start the upgrade procedure of the specified environment:
    $ octane upgrade-env <env id>

Expected results:
This command will provide ID of newly created environment with the same settings.

Actual result:
This command fails with the traceback:

Workaround:
Modify octane to use the openstack client instead of the keystone client.
