Thank you for all the help, I was able to create a tunnel on my test host.
My assumption is that for true Dynamic GRE creation via the OF Controller
attached to our test bed is that I will need:
1. A way to extract UUID info from the bridges that will be changed ( to
insert into the request).
2. A JSON Request string (template) with variable parameters to create the
tunnels. (finished this today)
3. A JSON Request string to delete tunnels no longer in use.
