New upstream release.

There are not many exciting news for Fedora though. Here are the highlights:

• when cloning content from git repos (like comps etc.), the logs will contain exact commit SHA that was used
• when consuming modules from Koji, Pungi will no longer fill in details into the modulemd file, and instead get the final file from Koji as it is uploaded there by MBS
• starting Koji runroot tasks has been refactored a bit, opening the doors to possible alternative implementations not depending on Koji

New upstream release:

• Git references are now resolved for kickstart urls in image build phase. All SCM dicts now also go through this resolution.

• Config validation script can now handle JSON files.

• Dumped configuration can now freeze a particular Koji event.
