(* XXX(dinosaure): [git_client] seems bad but it becames from a long discussion
when a "mimic" device seems not accepted by everyone. We can copy [git_happy_eyeballs]
and provide an [http_client] instead of a [git_client] but that mostly means that
2 instances of happy-eyeballs will exists together which is not really good
(it puts a pressure on the scheduler). *)
