Also update extras in setup.cfg.
This required some care. There doesn't seem to be a sane Python3 ready comment-preserving ini parser around, so I wrote a minimal-for-our-case one in Parsley. Parsley is already in use in infra in bindep, but I need to add it to global-requirements as this is the first use in a managed project of it. Change-Id: I48de3a2f36e945f75b534f689e3af802bbdc5be9 Depends-On: I7d7e91694c9145fac0ddab8a9de5f789d723c641 Depends-On: I16e967356d5c56f1474ee661b954b3db11a608cb
