We want to add the option for a user to have a more restricted view of
Notify.
This should be opt in/out on a per service basis, because it will be
appropriate only for a minority of teams. It shouldn’t be the default
because most teams (those without a lot of users or those only using the
API) won’t need it.
So this commit adds it as a new service permission, which means we can
roll it out:
- in prototype form initially
- then as an opt-in service setting
