[ ] update docs/readme
[ ] make swapfile creation, size, etc configurable
[ ] changes under review (288759) don't add for overcloud, as we run into space issues. Determine what (if anything) needs to be done for overcloud
[ ] determine if we should (optionally) allow for re-sizing the partition (overcloud + overcloud) as a configuration parameter.

We've been running into various issues with virt HA deployments, and have recently been needing to run the UC at 16-30 GB ram. The swapfile created is presently hard coded to 4GB, when it should really scale as 0.5 * UC memory size. This won't affect image size (of the qcow).
