Use dictionary for service group mappings Change the 'cloudkitty_service_names' from a list to a dictionary mapping of services, groups that install those services. This brings the method into line with that used in the os_neutron role in order to implement a more standardised method. The init tasks have been updated to run once and loop through this mapping rather than being included multiple times and re-run against each host. This may potentially reduce role run times. Currently the reload of upstart/systemd scripts may not happen if only one script changes as the task uses a loop with only one result register. This patch implements handlers to reload upstart/systemd scripts to ensure that this happens when any one of the scripts change. The handler to reload the services now only tries to restart the service if the host is in the group for the service according to the service group mapping. This allows us to ensure that handler failures are no longer ignored and that no execution time is wasted trying to restart services which do not exist on the host. Finally: - Common variables shared by each service's template files have been updated to use the service namespaced variables. - Unused handlers have been removed. - Unused variables have been removed.

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.
