* local-dev: implement local development environment this commit copies the files in /init into /local-dev, edits those files to support hot-reload features for local development, and introduces docker-compose/makefile targets in order to support local dev. Signed-off-by: ldelossa <ldelossa@redhat.com> * local-dev: hop quay workers to gunicorn this commit adds a uwsgi worker application delegate and a factory function allowing each worker to be ran by gunicorn. each worker now supports hot-reload and will reload itself when it's code is updated. this changes only affects the local dev env.
