Add support for cobbler >= 3.3.3

[meaksh]

What does this PR change?

This PR does the necessary adjustments to work with latest cobbler versions >= 3.3.3:

• Adjust custom "sync_post_tftpd_proxies.py" cobbler module to new API.
• Remove deprecated next_server cobbler setting in favor of next_server_v4 and next_server_v6.
• Adjust names for available fence agents
• Adjust testsuite scenarios to new fence agents names
• extend the already implemented Cobbler steps to include checking for profiles
• add tests for Cobbler buildiso

IMPORTANT NOTE: DO NOT MERGE THIS UNTIL COBBLER 3.3.3 IS PUSHED TO UYUNI AND HEAD

Do you want me to test the kickstart process on an Alma8 instance or is this expected to work? If yes, is this ready to test or should I wait?

[SchoolGuy]

@sbluhm Sadly this is still not in a working state. Also we are blocked until I have resolved https://github.com/cobbler/cobbler/issues/3016 both upstream and downstream.

[sbluhm]

@SchoolGuy thanks for the info. Offer still holds. Just let me know if/when.

@SchoolGuy, @meaksh: FYI: I have created my Cobbler buildiso tests against this branch and opened another PR for it: #5142. When you are ready with this PR, please merge my PR first into master-fixes-for-new-cobbler and then merge yours into master.

[SchoolGuy]

@meaksh I found out that uyuni/utils/spacewalk-hostname-rename utilises the old settings file. Thus this change is missing on this PR. I will prepare a commit for this later.

[SchoolGuy]

I rebased this onto master and pushed a few of my WIP changes along the way. Let's see how the testsuites like that while I continue implementing the new additional object features.

[SchoolGuy]

Rebased onto master to solve the conflicts.

[SchoolGuy]

@sbluhm I am not 100% sure but I believe testing this PR is of interest for you.

[sbluhm]

YES! So I guess it is ready for testing? Unfortunately EL9 doesn't install anymore due to a PostgreSQL issue so might take some time.

[SchoolGuy]

@sbluhm Yes it is. It will be merged for SUMA 4.3.1 so this week if my colleagues agree.

[sbluhm]

@SchoolGuy ok that is probably a bit tight for me. So will test in my own time and submit changes to master as usual. Thanks for this one!

[SchoolGuy]

@sbluhm Since some test failed we pushed this to 4.3.2, thus you know have a lot of time to test. I don't expect changes in the code atm, only fixes to the Java Unit-Tests. Feel free to prove me wrong. :D

[SchoolGuy]

@sbluhm Addendum: I prepared a project for you to test - https://build.opensuse.org/project/show/home:SchoolGuy:branches:systemsmanagement:Uyuni:Master

[SchoolGuy]

This seems stable enough now. Merging it now.
