Better Docker

Improves the Docker experience by leveraging Data volumes, dropping root permissions, using a more lightweight and secure base image (node:alpine), and moving unwieldy run arguments into a docker-compose file. The net result is you can now issue a single command `docker-compose up --build` to have a fully-functional verdaccio instance running.
