This PR has huge non-isolated change which make it difficult to review, I suggest breaking it up to change only closely related things.

@gdevenyi Besides the .editorconfig and package.json URL updates, everything else is required to get the Docker environment up and working. I included the documentation since I could not find a migration tool in the current packages, but feel free to break it down into multiple PRs.

As per my PR, the changes are far less extensive to get the docker working. Only thing missing in mine is readme changes to change the databasename and password in the 6_usermanagement.sql
