web API: whitelist swh-team machines

Until T1927 is fixed, it would be useful to lift the rate-limit on the Web API for swh-team members (I personally have an immediate need for it, i.e., T1926 development, but I think it's a more general need that might help all staffers).

As a first approximation maybe we can whitelist all local Inria IPs? (not sure what's the exact ranges are though…) Alternatively we can gather the list of IP addresses of all our machines, including personal laptops, and whitelist all of them.
