Enable support for hardware that brings the network up slowly

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.

+============
+Slow Network
+============
+
+This element is used to configure network start for network devices that take
+longer than normal to start (LACP for example).
+
+* You can use the `NETWORK_TIMEOUT` environment variable to set the timeout.
+  The timeout currently defaults to 60.
