[ovirt-devel] AppErrors cleanup

Hi all, A recent bug [1] reported as part of the translation effort alerted me to the fact that we have a lot (and I mean a LOT - over 100 per file) of deprecated, unused keys in the various AppErrors files that serve no purpose and just take up space and waste translators time when they examine them. To make a long story short - I've just merged a patch to remove all these useless messages, and enforce via unit tests that EVERY key there should have a corresponding constant in the EngineMessage or EngineError enums. Many thanks to my reviewers! I know this was an tedious patch that couldn't have been too fun to review. -Allon [1] https://bugzilla.redhat.com/show_bug.cgi?id=1244766
