Disable Rack::Attack throttling by default in Component::Gitlab
This disables the Rack::Attack throttling by default in Component::Gitlab. See https://docs.gitlab.com/ee/security/rack_attack.html#protected-paths-throttle.
For now, I don't think we have any scenarios that test the throttling itself so I thought it's acceptable to disable it by default entirely like that.
In the future, we could change the #omnibus_config= method so that the default config wouldn't be appended on the case we want to test the throttling.
