[SLE15-SP6] Better summary for the SLE_HPC => SLES upgrade (jsc#PED-7841)

[lslezak]

Problem

• Related to SLE HPC is not a base product anymore (jsc#PED-7841) #650, https://jira.suse.com/browse/PED-7841

• The display product summary at a SLE_HPC upgrade was not perfect:

  • New SLES will be installed
  • SLE_HPC will be upgraded to HPC module
    

• That is technically correct, but it actually is SLE_HPC => SLES base product upgrade/migration and the HPC module upgrade to a newer version

Solution

• Update the product rename mapping

Technical Details

Originally it was "SLE_HPC" => ["SLES", "sle-module-hpc"] mapping. But because the old SLE_HPC required the HPC module (a hard dependency, you cannot have SLE_HPC without the HPC module) then the real upgrade is not "SLE_HPC => SLES + HPC" but rather "SLE_HPC + HPC => SLES + HPC". And in that case we can remove the HPC module from the mapping because it will be automatically upgraded to the new available version.

If the HPC module was optional for SLE_HPC we would have to add it to the mapping, but as it was mandatory we can leave it out.

That mapping is used when finding the product upgrades for the upgrade summary. The extra HPC value confuses the algorithm and it thinks the SLE_HPC is upgraded to the HPC module.

Testing

• Tested manually
