* Allow nom_build to run in Cloudbuild
Our builder comes with python3.6 and cannot support nom_build out of
box. Nom_build requires dataclasses which is introduced in v3.7.
I haven't found an easy way to get python3.7+ without changing the base
linux image. This PR explicitly installs dataclasses.
The node installed by nvm gives errors when running "npm install".
Also installs Python as it is need. Presumbly the system provided npm
version has python as a dependency so it was installed when npm was
installed.
We need to first populate the apt sources before installing anything. It was working on my machine because the layer was cached. After I purged all images I was able to replicate the same error message.

The pipeline is broken into two. The first one is to be triggered when the public repo is tagged. It then tags the private repo, builds and upload the builder and base images, and push a new commit to the release (merged repo). This pipeline also does text manipulation on several files in the release repo to ensure that the images uploaded in this pipeline is always used to reproducibly build the release repo at the same commit.
The second pipeline is then triggered by commit into the release repo, which builds, signs and uploads the proxy image.
Also updated the dependency lock files to use the latest plugins dependencies, which are uploaded to the GCS repo.
