This is a #tracking task.
Node 4.3 is available on Nodepool instances. It is time to carefully switch the various services to it (from Trusty and node 0.10.x). We have to migrate the source and deploy repositories jobs from the `npm` / `XX-deploy-npm` jobs to the new `npm-node-4.3` and `XX-deploy-npm-4.3` jobs.
In some cases, the deploy repository does not have any job which might prove challenging since the CI configuration is a bit scary (for deploy repos, the dev dependencies are injected from the source repo and a symlink package.json -> src/package.json needs to be present).
