This PR prepares the ground for the one introducing guests
for livechat visitors. Since our SameSite cookie policy
is Lax, the cookie won't be send on unsafe cross site
requests thus another mechanism will be introduced to
retrieve the guest.
This PR abstracts the way the guest is retrieved in order
to ease this transition as much as possible by overriding
the `ir_http._pre_dispatch` method in order to inject the
guest in the context if any.
