In order to cater for artifact-based installed, and rolling upgrades, this patch implements a set of local facts to inform the online migrations task. The 'nova_all_software_updated' variable will be set by the playbook on each run to ensure that the online migrations only happen once all venvs are homogenous. This ensures that the playbook can be executed in a serialised fashion and the data will not be corrupted. The ``upgrade_levels`` setting for ``compute`` is set to ``auto`` to ensure that a mixed RPC version deployment can operate properly when doing a rolling upgrade as suggested by [1]. Additional changes are made to improve the role's ability to be executed using serialised playbooks. Finally, the nova-manage command references to the config file location have been removed as they refer to the default location.
