Delaying KF 5.21

[David Faure]

I don't feel good releasing KF 5.21 with 14 failing builds in the CI.
Let's fix CI first, then we can release.

I'm debugging the kservice unit test failure, which is an actual bug (not a CI problem).

I'll also try to debug the kcoreaddons mimetype issue, that one being a CI problem.

KTextEditor people, please take a look at
https://build.kde.org/view/Frameworks%20kf5-qt5/job/ktexteditor%20master%20kf5-qt5/13/PLATFORM=Linux,compiler=gcc/console
and please don't wait for me to play unittest police, you can keep an eye on the CI without me...

Plasma people .... err ... why isn't plasma-framework listed on
https://build.kde.org/view/Frameworks%20kf5-qt5/ anymore?
I see that plasma-framework is green again though, well done.
I'm just very worried if that view doesn't have all of the frameworks anymore.
Would sometime have the time to go through the list and check what else is missing?
