Upstream the PolyGerrit plugin for Checks. This is just a basic buildable and runnable copy of the experimentally devloped plugin. There are some obvious remaining TODOs: * Rename build-result to checks everywhere. * Integrate PolyGerrit plugin into the backend plugin jar. * Hook up with the new Rest API endpoints for checks.
