Add the slow-network element which defaults the timeout of network
bring-up to 60 seconds set by the NETWORK_TIMEOUT environment variable.
Syncs the ops repository to a known location so that we can use the
element when building images.
Rename the register-images script to register-nodes as that what it
actually does.

The image generation script will generate centos xenial and trusty
images along with the deploy image. It will then upload the images into
glance and clean up after itself, other then the pacakges needed for
diskimage-builder and virtualenv this is all contained and easily
cleaned up.
The node registration script relies on the image generation script being
run first. It will create flavors if needed, but the values for some of
the variables are designed to be modified (image_ram/cpu for example).
