On "./pup-tests.sh create" SSH keys will be created and placed on
the webserver and backup server to allow the backup server to
restore files back to the webserver easily.
If a forge module is added to the Puppetfile after the pup-tests
script is used to "create" the environment, pup-tests "apply" will
now download and install them.
Created a new backup virtual machine server called "backups" with a
simple configuration using the Getting Started with Amanda tutorial.
README also updated to reflect new workflow.
