Drop python3.6 support.

Commits for dropping 3.5 support to copy from:

c245b7d855ccd "Initial drop of Python 3.5"
ccdfb44b8568b "Drop support for Python 3.6.0"

Anything needed to update regarding OS version support in
doc/install.asciidoc?
TODO: remove 3.6/7 annotations in requirements files and
  rebuild

workflows: not sure I updated it right (run 5.12 with 3.7, same 18.04 OS) but
18.04 seems to have 3.7 on it too so it should work. It'll all change when we
drop <5.15 anyway. Not sure what the minimum ubuntu version will be going
forward.

Regarding mimetype overrides (ebb3046822adb) the doctring says they can all go
in 3.7 but .h5 is still missing on py39, not sure if we should care.

There are a bunch of old(?) warning messages still ignored in tests/end2end/fixtures/quteprocess.py.
