MySQL doesn't allow us to create a trigger for a column that doesn't
exist yet. Failing with this error:

```
Mysql2::Error: Unknown column 'build_events' in 'NEW': CREATE TRIGGER trigger_6a80c097c862_insert
BEFORE INSERT
ON `services`
FOR EACH ROW
SET NEW.`build_events` = NEW.`job_events`
```

Creating the new column before creating the trigger avoids this.

Variables shouldn't exist without a project, so a foreign key was added
with CASCADE'ing effects.

This makes it more obvious that we greatly prefer PostgreSQL over
MySQL/MariaDB and that all users are recommended to use PostgreSQL
instead. This also removes the paragraph mentioning the size per user
row, as this is completely inaccurate and doesn't really help users with
anticipating the database size. Instead we now simply recommend users to
have at least 5-10 GB of storage at minimum.
