Merge branch 'gitlab-with-emulator-23' into 'master'

gitlab-ci: use android-17 emulator for `gradle connectedCheck`

The android-10 emulator does not report test failures so it is pretty useless at the moment.  After lots and lots of trying, the most recent emulator that I could get running on gitlab-ci was 17, so let's hope that turns out to be more useful.  I also had to reduce the RAM that was used, it seems that gitlab-ci does not let the docker images use much RAM.  This might be able to be improved by creating an pre-setup AVD image in the docker image used by this.

As you can see from the history, I tried lots of things to see if it is was possible to get a more recent emulator running on gitlab-ci.
