Implement the contacts prohibited feature flag for minimum data set (#2781)

This prohibits all contact data on create and update EPP flows for both domain
and contact flows. It also refactors how default values on FeatureFlags work, as
it's safer to specify a single default on the flag itself rather than have to
specify it independently at a number of callsites (and potentially end up having
an inconsistent value). Domain updates on existing domains that still have
contact data will fail unless all contact data is removed, as a forcing function
to require registrars to rectify the situation prior to being able to do any
other kind of domain changes.

Contact-related flows that are still allowed after this point: Updating a domain
to remove all contacts from it, and deleting a contact object.
