Due to changed default database credentials and database name in
`docker-compose.yml`, a previous installation needs to be migrated in
order to work with the new defaults.

Split dockerfiles into stages

This improves caching and readability without compromising the final
image size.

This patch should help to ensure that there is always an up-to-date
nightly build.

During release 1.7.1 the official release was containing more recent
changes than the latest nightly. This is an undesierable situation,
which this patch should fix by adding "on push" as trigger for the
nightly action.

This patch adds a "lateset"-like tag to the build to simplify continous
deployment setups, such as our demo instance.

Remove all content from config.json

Because of a bug in sequelize, the hardcoded name of the database in config.json was used with mysql/mariadb databases. This commit removes all content from config.json, so environment variables are always used. The file itself must still exist, as HedgeDoc does not start without a config file.

Fix pin-rebuild-pin loop

This patch should fix the pin-rebuild-pin loop, that appears due to each
change in the repository resulting in a new image build, which results
in a new pin in the docker-compose file, which results in a merge, that
triggers a new build.

Instead this patch excludes the `docker-compose.yaml` from pinning and
solves the issue.
