This removes the systemd service templates and tasks from this role and
leverages a common systemd service role instead. This change removes a
lot of code duplication across all roles all without sacrificing features
or functionality. The intention of this change is to ensure uniformity and
reduce the maintenance burden on the community when sweeping changes are
needed.

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:

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.

Using ansible systemd module to daemon reload and service reload
is the solution for the future. Let's embrace it!

Ansible 2.2 now treats the 'name' argument for the pip module
as a list, removing the need for us to implement the join
filter to optimise the install execution.
