remove rate limiting for curators

[michielbdejong]

if the logged-in user is a curator, we probably shouldn't need to rate limit them

[madoleary]

Leaving this here as a potential solution to explore : rack/rack-attack#397

[michielbdejong]

Tried changing req.ip to req.ip unless current_user.curator? in each of the throttle rules in config/initializers/rack_attack.rb but current_user is not available there.

As a work-around for now I'll temporarily loosen the update-document limit for everyone for now, because that's the one we will be hitting while reviewing old pending points and old doc crawls.
