This patch refactors the whole monasca role by bringing consistency
with the other openstack-ansible roles. Main changes include:
- Install services on its specific cointainer;
- monasca-thresh, monasca-notification and monasca-persister was
not being installed/configured, now it is;
- Tempest tests are ran for the whole monasca-api;
- The service should be fully functional;
- Added documentation.
The extras directory contains the changes necessary to openstack-
ansible to setup monasca.

The systemd unit 'TimeoutSec' value which controls the time
between sending a SIGTERM signal and a SIGKILL signal when
stopping or restarting the service has been reduced from 300
seconds to 120 seconds. This provides 2 minutes for long-lived
sessions to drain while preventing new ones from starting
before a restart or a stop.
The 'RestartSec' value which controls the time between the
service stop and start when restarting has been reduced from
150 seconds to 2 seconds to make the restart happen faster.
These values can be adjusted by using the *_init_config_overrides
variables which use the config_template task to change template
defaults.

This creates a specific slice which all OpenStack services will operate
from. By creating an independent slice these components will be governed
away from the system slice allowing us to better optimise resource
consumption.
See the following for more information on slices:
* https://www.freedesktop.org/software/systemd/man/systemd.slice.html
See for following for more information on resource controls:
* https://www.freedesktop.org/software/systemd/man/systemd.resource-control.html
Tools like ``systemd-cgtop`` and ``systemd-cgls`` will now give us
insight into specific processes, process groups, and resouce consumption
in ways that we've not had access to before. To enable some of this reporting
the accounting options have been added to the [Service] section of the unit
file.
