Dropping support for 2.7 in 2020

[Emmanuelle Gouillart]

Just to be clear: I very much hope that we'll have lots of great releases
until 2020 so that users bound to legacy 2.7 will be happy with a
not-so-up-to-date release. It's just that I trust us more to produce
these releases than big institutions to make their systems evolve!
