[6.15.z] Fetch pre_upgrade data based on node properties

[Satellite-QE]

Cherrypick of PR: #16423

Problem Statement

During TFA I've seen several post_upgrade failures for "rhel_contenthost-parametrized" upgrade scenario tests where the pre-data could not be fetched from the scenario_entities file:

failed on setup with "Failed: Invalid test parameter: rhel7. Test data not found."

The reason is that the pre-upgrade test names are now suffixed with -ipv4 or -ipv6 so the scenario_entities hold items like this:

{"tests/upgrades/test_repository.py::TestSimpleContentAccessOnly::test_pre_simple_content_access_only[rhel7-ipv4]": {...}}

while this piece of code requires the exact param, which is just rhel7, rhel8, rhel9.

Solution(?)

There are probably more than one solution and I'm not sure which one would be the best.

Initially I thought we could go regardless the ipvX suffix since I supposed the pipelines were separated (first commit).
That's probably not a good solution when we start decorating tests with ['ipv4', 'ipv6'] explicitly, so I took the network type from the settings.

Please let me know if there is a better place where to get that information from in scope of the pre_upgrade_data fixture.
