Assess Fedora 26, retire old Fedora

..is out. We should probably test on it.

FYI if someone wants to tackle this, ansible is the place to contribute.

As of yesterday Fedora 24 was retired, so we're now running 3 out of date versions - 22, 23 and 24, and we really should get rid of those. Does someone with Jenkins access want to disentangle them from the various jobs?

My contribution hours will change in roughly a month so expect me to vacuum the bug tracker unless anyone beats me to the punch (anon: i know you can do it!).

We currently have Fedora 27 in CI now and #962 is an open issue to retire 22, 23, and 24.

I'm going to close this, but please re-open if that's not the right thing to do.
