Consolidate the Local Docker installer and the dev env

- removes local_docker installer and points community users to our development environment (make docker-compose)
  - provides a migration path from Local Docker Compose installations --> the dev environment
  - the dev env can now be configured to use an external database
  - consolidated the Local Docker and dev env docker-compose.yml files into one template file, used by the dockerfile role
  - added a 'sources' role to template out config files
  - the postgres data dir is no longer a bind-mount, it is a docker volume
  - the redis socket is not longer a bind-mount, it is a docker volume
  - the local_settings.py.docker-compose file no longer needs to be copied over in the dev env
  - Create tmp rsyslog.conf in rsyslog volume to avoid cross-linking. Previously, the tmp code-generated rsyslog.conf was being written to /tmp (by default).  As a result, we were attempting to shutil.move() across volumes.
  - move k8s image build and push roles under tools/ansible
  - See tools/docker-compose/README.md for usage of these changes
