Change: Add upgrade scripts for database files
Postgres changes the format of the database files on disk between major versions. This means that in order to upgrade a postgres database, it is not sufficient to just bump the container versions. To help with this process, we now can use migration scripts that will take care of updating the database version without the need of a manual dump/restore. Ref.: DEVOPS-1292

The previous version of the test needed to be changed for every new version of postgres, now we are using variables to template most of the behavior.

Change: Build fresh image as part of the test
This ensures no stale image is used on accident.

Fix: Migrate old authentication settings
Authentication settings are not migrated automatically, according to the documentation. The authentication is non-standard, if the database was created with the initdb script inside a docker container. To prevent problems with this, we will copy over the old pg_hba.conf file, which seldomly changes.
