WP-CI: Uyuni/Head: Bump all minions from sles15sp4 to sles15sp7

[maximenoel8]

What does this PR change?

Bump everything sles15sp4 to sles15sp7. Including:

• build host
• terminals
• pxeboot
• docker => changed the way to select the environment to be more dynamic (I enter "([^"]*)" relative to profiles as "([^"]*))
• sync and channel testing sles15sp7
• I had issue with the sles15sp4 installer module, it doesn't exist in sles15sp7 so I use container module for the similar test
• Also proxy extension is in slmicro6.1 product or sles15sp7 product now and not a standalone product
• changed the autoyast to deploy sles15sp7 with salt bundle
• changed the tftpboot package

Fixes including in this PR:

• cleaning terminals for retail mass import -> switch to API
• exporting rake parallel result in the correct result folder
• cleaning channel in content cycle, use the option a (I delete these channels( with children)? with spacewalk-remove-channel)
• fix a drop down selection (I select "([^"]*)" from drop-down in table line with "([^"]*) )
• and more !

What left to do:

• find ptf compatible with sles15sp7 for lotus project
• check new ptf testing from Wiktor (credentials were missing in personal pipeline)
• pxe boot bootstrap using script is still failing
• check for other side effect

[github-actions]

👋 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/11258/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/11258/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.

Happy hacking!
