Within the multi-node-aio-xenial-ansible folder the multi-node-aio
content has been copied over, Cobbler and Trusty specific parts have
been removed.
The intent here is to replace much of the bash which is present with
Ansible and not support Trusty. To do this a clean separate folder is
required so large changes which are made will not affect the current
working Trusty based install.
