Clean up tests a bit

1. Remove tests/test-configure-octavia.yml because the 'shade' package
   does not need to be installed again - this is already done by the
   role test preparation.

2. Remove the key generation as the keys are already generated in the
   common tests playbook 'test-prepare-keys.yml'.

3. Add some spacing between tasks to make it more readable.

4. Implement the extra packages needed in test-requirements.txt instead
   of trying to use a task to install them, because doing it in Ansible
   makes understanding the venv in relation to the inventory complicated..

5. Move the vars_files argument to the top of the play to make it easier
   to find and more uniform with other plays in OSA.

6. Switch from using octavia_ansible_endpoint_type to a hard-coded
   endpoint, then remove the octavia_ansible_endpoint_type var.

7. Switch from using the 'endpoint_type' argument for the openstack
   modules to using the more modern 'interface' argument.

8. Remove the 'run_once' argument on the 'Upload key to nova' task
   because only localhost is targeted, so the argument is moot.

9. Remove the 'Set VIP fact' task in favor of just using the 'vip_output'
   register in the 'Test the Listener' task. Setting a fact is pointless.

10. To help the existing patches pass, we add python-pip to the distro
    packages. This will be reverted later once the required changes
    to remove this requirement have merged.
