Integration tests: include MariaDB as well

[Al2Klimov]

just to be sure we're compatible with this RDBMS and not only MySQL.

While this PR was somewhat forgotten, I just thought about it in spite of #947. How about testing both the latest version as well as the minimum required version for each DBMS?

They're either not available or don't work and it's a bit out of scope here.

I wouldn't understand that comment if I didn't happen to look at this PR and it's pipelines at just the right moment by pure chance, i.e. at this run: https://github.com/Icinga/icingadb/actions/runs/17097225377

One job failed because there seems to be no mariadb:10.2.2 image on Docker Hub:

panic: Error response from daemon: manifest for mariadb:10.2.2 not found: manifest unknown: manifest unknown

The other one failed with a MySQL error:

panic: Error 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ON . TO u1 */' at line 1

This also needs more context: that's an error from the database setup done by icinga-testing.

Fixing that is trivial actually (if you know where to look), so I just created a PR for it: Icinga/icinga-testing#32

Again, what is the state of this PR, @Al2Klimov? Do you want to proceed here? It was quite hard for me to follow the conversion, especially with the time gap in between.

[Al2Klimov]

Well, you asked #729 (comment) for also including the minimum required RDBMS versions, but this seemed not to work. I've rebased and hope for the best...

[lippserd]

Let's be honest, this is more or less a waste of resources. I would close the PR.

[Al2Klimov]

But all checks pass now.
