Multiple updates. Converted many of the Yaml files from "dos" format to
"unix" format. Finalized the creation of the final installer file set
that can be copied to a USB Flash drive or other removable media.
Updated the config file with comments to make it more user friendly.
Deleted ansible files that were no longer needed. This update continues
to address the requirements laid out by Jira VOL-6.
