infinitepush: opt out of changegroup3 unless explicitly configured
This is currently a no-op, as changegroup3 is disabled by default. But when it
is enabled, it changes the hash names of the bundle files. As I don't use this
extension, I have no idea if that's OK or not. So keep the current default
behavior until we can get more info from actual users, while allowing them to
opt-in for testing purposes.
