* 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.
Defined Docker image for schema deployment.
Included schema deploymer docker in the Cloud Build release process.
Defined Cloud Build config for schema deployment.
TESTED=Used cloud-build-local to test deployment flow
TESTED=Used docker to test schema deployer image in more ways
* Save release tag during deployment
* Save current tag for every environment
Store tag of the current deployment in each environment.
This is used by the server-sql compatibility test.

* 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.
