Fix monitoring ent detection

[mcalmer]

What does this PR change?

On Oracle Linux the OS Release is a 2 digit number. Our isRedHatX detection uses the family but expected only a single number.
Now we use a startsWith() to also detect sub releases.

This PR simplify also the OS release detection. We simply use what the grains will report to us instead of trying to stay compatible with the traditional stack.

👋 Hello! Thanks for contributing to our project.
Acceptance tests will take some time (aprox. 1h), please be patient ☕
You can see the progress at the end of this page and at https://github.com/uyuni-project/uyuni/pull/9590/checks
Once tests finish, if they fail, you can check 👀 the cucumber report. See the link at the output of the action.
You can also check the artifacts section, which contains the logs at https://github.com/uyuni-project/uyuni/pull/9590/checks.

If you are unsure the failing tests are related to your code, you can check the "reference jobs". These are jobs that run on a scheduled time with code from master. If they fail for the same reason as your build, it means the tests or the infrastructure are broken. If they do not fail, but yours do, it means it is related to your code.

Reference tests:

• https://github.com/uyuni-project/uyuni/actions/workflows/acceptance_tests_secondary_parallel.yml?query=event%3Aschedule

• https://github.com/uyuni-project/uyuni/actions/workflows/acceptance_tests_secondary.yml?query=event%3Aschedule

KNOWN ISSUES

Sometimes the build can fail when pulling new jar files from download.opensuse.org . This is a known limitation. Given this happens rarely, when it does, all you need to do is rerun the test. Sorry for the inconvenience.

For more tips on troubleshooting, see the troubleshooting guide.

Happy hacking!
⚠️ You should not merge if acceptance tests fail to pass. ⚠️

I think this method is only use in the places you have removed the call. Can this method be removed at all?

[mcalmer]

yes, and there are more unused functions now. I will adapt this
