Make it possible to migrate database schema

[rija]

User story

As a developer
I want to be able to upgrade the database schema for new migrations independently from resetting database
So that I can upgrade the schema for a running database (like the one on live production)

Acceptance criteria

Given there is a new migration file merged with schema changes
When the Gitlab pipeline is run
Then I should see a new operational job to run the migration on existing database

Additional Info

At the moment, the migrations are executed when databaseReset is run.
We still want that to happen, but we also want to be able to run them separately.
Mostly because we cannot run databaseReset on live production, and it's better for the operation to be visible
an controllable on the Gitlab pipeline.
