Proposal to CANCEL: 2019-04-15 Fedora QA Meeting

Hi folks! I'm proposing we cancel the QA meeting on Monday. I think we
covered everything already, but if you're aware of anything important
we have to discuss this week, please do reply to this mail and we can
go ahead and run the meeting. Note there *will* be a blocker review
meeting, and of course, doing Final validation testing is a great thing
everyone can be doing right now :)

Thanks, everyone!
