XD-321 implement TapController.create() and .deploy()
Fixed gradle launch ./xd-admin problem
XD-364 - Create Trigger Registry

* Create Trigger Controller (REST Endpoint)
* Persist Trigger to Redis
* Create associated domain objects
Updated to support Restful deployment of Jobs
Introduction to source control
Rebasing to test with taps.
Rebase again
Added Tests to the controller.
Also Had a debate (and yes I debate myself).  For now with jobs they will auto start once the job has been deployed.  I didn't think we had to go with the extra step since they are timed.
Add the tests (as enumerated in the last checkin).  Added the Job in memoryJobDefinition for the single node instance.
