Extracts the common role into a separate play. This provides a performance
benefit at scale, since the role dependency mechanism used previously had a
overhead. This change allows the only common role to be executed by
specifying the ``common`` tag.
upgrade:
- |
The common role is now executed in a separate play. This introduces a few
small changes in behaviour:
* the common role is now run for all hosts at the beginning, rather than
prior to their first enabled service
* hosts must be in the necessary group for each of the common services
(``cron``, ``fluentd``, ``kolla-logs``, ``kolla-toolbox``) in order to
have that service deployed
* if tags are specified for another service e.g. nova, the common role
will *not* automatically run for matching hosts. The common tag must
be specified explicitly
