WIP: Don't die if releasenotes URL is not available

[rakoenig]

• poo#97316: Sometimes URL for release notes is not yet available
  for SLES. In this case record a soft failure instead of dying.

• Related ticket: https://progress.opensuse.org/issues/97316

• Verification run:https://openqa.suse.de/tests/7100006

for applying in Full offline test suite, if you can just pass SCC_REGISTER', 'installation' and the test suite remains unaffected I would go for that path, if more changes are needed, then it would be to hacky and I think it is better to create additional module for that case.

I now put the code back to just record a soft failure with referencing the poo#97316 ticket. The logic if looking for RPM or URL is stll the same relying on SCC_REGISTER, just to avoid breaking existing old job definitions.

Could you please try as well the second part of the ticket and provide a verification? 'schedule the module to offline installation test suite' to see if we need to do further changes or not.

btw, you have some extra commits from previous work (probably some missing rebase).
