* Work around Spinnaker issue wrt variables
Cloud Build variable reference need to stay from the ${var} pattern
to prevent Spinnaker from trying to resolve it. In all files that
are used by Spinnaker, we change variable reference to the $var form.
We made the minimum amount of change possible, and will review this
issue after the permanent solution is available.
* Merge beam and GAE configs deployment to one GCB job
Deployment of GAE configs requires that the credential used by gcloud to
have GAE admin role of the project to be managed. We do not want to
grant the GCB service account that role, because it would all *any* GCB
job to deploy anything to GAE. Instead we use a dedicated credential
originally created to deploy beam pipelines. This credential is
encrypted by KMS and stored on GCS. Since the beam pipeline deployment
GCB job already does the decryption, it make sense to add the config
deployment step there as well. The beam deployment steps are tweaked to
use the nomulus tool docker image instead of the jar file.
Also moved the content of deploy_configs_to_env.sh to the GCB yaml file
itself because the shell script is not uploaded to GC Bat the same time
as the yaml file when the job is triggered by Spinnaker.
Lastly, due to b/137891685, using GCB to deploy cron jobs does not work
as we cannot use service account credential to deploy to projects under
google.com.
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.
