Since inventory ships with kargo, the ability to change functionality
without having a dirty git index is nice.  An example, we wish to change
is the version of docker deployed to our CentOS systems.  Due to an issue
with tiller and docker 1.13, we wish to deploy docker 1.12.  Since this
change does not belong in Kargo, we wish to locally override the docker
version, until the issue is sorted.

Ensure vagrant uses flannel

The Vagrantfile is setup to use flannel.  The default network
was changed to Calico (#1031).  However, the Vagrantfile was
not updated to reflect this.  Ensuring the Vagrantfile remains
functional on master, until someone decides to make it work
with Calico.
