If the playbook is run multiple times or a host already has
swap configured, re-adding swap over the existing file
will cause untold problems. Also, it will not persist across
reboots unless added to fstab.
Avoid this by checking if any swap is active. If not
create a unique swapfile and format it. Then enable
it to persist across reboots.

Packages are no longer available to build on RHEL and CentOS and
btrfs is not longer supported, so we should not build with it.

It's unsightly and hard to maintain collections of references and long
lists across multiple playbooks/include files. Centralize them all
in ``vars.yml``, then include that in all plays.
Minor: Update all files with a newline at the start and end.
