As branching 0.21.0 off is approaching it seems a good time to discuss a possible bumping of the minimum required Qt5 version.

The current minimum required Qt is 5.5.1. Set in #15393. Recent discussion in #13478.

Distro support:
- stretch -- 5.7.1
- buster -- 5.11.3
- bionic -- 5.9.5
- focal -- 5.12.8
- centos 7 -- 5.9.7
- centos 8 -- 5.12.5
Bumping to 5.9 (LTS) is possible, but it won't be of much benefit to us. Also, its support ended on 2020-05-31.

5.10 could bring much more benefits to us, e.g.:
- functor-parameter overload of QMetaObject::invokeMethod
- fixed https://bugreports.qt.io/browse/QTBUG-10907

I'm for bumping the minimum required Qt Version seeing as the last bump was over 2 years ago. Furthermore, Qt 5.5.1 is ANCIENT.

Bumping to 5.9 should be completely uncontroversial, now that all systems that ship a C++17 compiler also ship with qt5.9+
