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.

+Docker will generate a named volume in which to store persistent application data. You can use `docker inspect` or `docker volume inspect` to reveal the physical location of the volume and edit the configuration, such as:
+ 
+```bash
+$ docker volume inspect verdaccio_verdaccio
+[
+    {
+        "Name": "verdaccio_verdaccio",
+        "Driver": "local",

+        "Labels": null,
+        "Scope": "local"
+    }
+]
 ```
 
 Please note that for any of the above docker commands you need to have docker installed on your machine and the docker executable should be available on your `$PATH`.
