* Build docker image of nomulus tool
In the course of "gradle build", build a docker image of nomulus tool so that
users can run this to allow us to bundle the java version with the image.
With https://github.com/spinnaker/spinnaker/issues/4048 Spinnaker now natively supports GCB. We are able to start a GCB job from Spinnaker, and also there is better support to consume GCB pub/sub messages. Some changes are made to remove the workaround no longer needed.
Two new workflows are added, one to rsync a GCS folder to live/ after the deployment is done (so that the nomulus.jar file can then be fetched to x20 by a []cron job), and the other to tag the proxy image as live once it is deployed.
Lastly, the docs/ folders are needed when running tests. Remove it from .gcloudignore so that when a test run is kicked off by running "gcloud builds submit" the folder is sent to GCB. Ideally .gcloudignore should be identical to .gitignore but since they both are version controlled it is hard it make one a symlink of another.

Refactor out the build and package logic to a reusable script. Also removed the gradle task flag to skip lint check, as failing lint check is no longer a fatal error.
