Build an uber tarball in Cloud Build

Spinnaker currently cannot have inter-dependencies between different pipelines.
As a result we put the WAR files for all environments in one tarball which
triggers a single pipeline that first deploys to sandbox and then to
production.

Temporarily disabled pulling dependencies from GCS while that is being worked
out.
