Update paste, policy and rootwrap configurations 2017-12-19
The locations of the previously included templates have been
moved to the standard location used in all other roles. This
helps to allow the sources-branch-updater script be able to
automatically place the updated files processed from the
upstream git repositories.
As there is now a rootwrap filter file, the appropriate tasks
to create the directory and to add the file have been
implemented. A little clean-up of syntax of tasks near those
modified have been included.
Finally - to resolve the ansible-lint issue the use of
systemctl has been removed.
