A new config flag is added that buckets 50% of users into the old
header and the 50% into the new header.

This will allow us to add the A/B testing requirement for logged in
users.
In preparation for the new A/B test requirement, a custom requirement
is added as the feature management system does not
support OR operations and the desired effect is the case where:
* the SearchInHeader feature flag has been enabled
* OR the SearchInHeaderABTest feature flag has been enabled and the user is bucketed
