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.
