removed heat from devstack installation (not used so want to save space)
setup docker to use zfs for backing store
setup docker to bind to port 192.168.27.100:2375 (now you can use your local docker install to execute commands on stackinabox)
setup docker to allow ipv4 port forwarding
setup docker to use 192.168.27.100 as default for all port bindings
setup docker to use lxd's lxdbr0 network bridge by default
comment out custimizations to dhclient.conf (not sure if they were even being used)
updated vagrant/build.sh file to expect execution from the vagrant folder (previously it expected to be called from the root folder which I found to be confusing so I changed it)
add a new disk to hold the /var/lib/docker zfs backing store (dynamic disk that will grow as needed up to 500GB)
Add support for running Docker within LXD Containers provisioned by OpenStack's nova-lxd driver
Update virtualbox guest image to latest version 5.2.1
Add Docker Heat plugins to heat server, now you can use Docker from your HEAT documents!
