Refactor that prepares kolla_container_facts
module for introducing more actions that will be moved
from kolla_container module and kolla_container_volume_facts.
This change is based on a discussion about adding a new action
to kolla_container module that retrieves all names of the running
containers. It was agreed that kolla-ansible should follow Ansible's
direction of splitting modules between action modules and facts
modules. Because of this, kolla_container_facts needs to be able
to handle different requests for data about containers or volumes.

Most roles are not leveraging the jinja filters available.
According to [1] filtering the list of services makes the execution
faster than skipping the tasks.
This patchset also includes some cosmetic changes to genconfig.
Individual services are now also using a jinja filter. This has
no impact on performance, just makes the tasks look cleaner.
Naming of some vars in genconfig was changed to "service" to make
the tasks more uniform as some were previously using
the service name and some were using "service".
Three metrics from the deployment were taken and those were
- overall deployment time [s]
- time spent on the specific role [s]
- CPU usage (measured with perf) [-]
Overall genconfig time went down on avg. from 209s to 195s
Time spent on the loadbalancer role went down on avg. from 27s to 23s
Time spent on the neutron role went down on avg from 102s to 95s
Time spent on the nova-cell role went down on avg. from 54s to 52s
Also the average CPUs utilized reported by perf went down
from 3.31 to 3.15.
For details of how this was measured see the comments in gerrit.

docker_restart_policy: no causes systemd units to not get created
and we use it in CI to disable restarts on services.
Introducing oneshot policy to not create systemd unit for oneshot
containers (those that are running bootstrap tasks, like db
bootstrap and don't need a systemd unit), but still create systemd
units for long lived containers but with Restart=No.
