Code Issues Proposed changes

Ensure the components are isolated from the system 

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.

features:
- New variables have been added to allow a deployer to customize
a neutron systemd unit file to their liking.
- The task dropping the neutron systemd unit files now uses the
``config_template`` action plugin allowing deployers access to
customize the unit files as they see fit without having to
load extra options into the defaults and polute the generic
systemd unit file with jinja2 variables and conditionals.
