Various fixes and improvements

Changes Include:
 - New Interactive mode.  Allows you to pause deployments in order to
make changes before continuing (or exit and deploy manually).  Useful
when needing to modify NIC order for baremetal deployments.
 - deploy_settings -d is now required.
 - ha_enabled no longer defaults to true.  It can be specified in
deploy_settings or overridden with via command line.
 - compute nodes now scale correctly with what is defined by inventory
