As discussed in https://github.com/smallstep/certificates/issues/767,
we opted for not including this authorization flow to prevent users
from getting OOMs. We can add the functionality back when the
underlying data store can provide access to a long list of
Authorizations more efficiently, for example when a callback is
implemented.
Refactored some of the existing bits for testing the Authority
API by creation of a new LinkedAuthority interface and changing
visibility of the MockAuthority to be usable by other packages.
At this time, not all of the functions of MockAuthority it usable
yet. Will refactor when needed or requested.
The logic for both test cases is fairly similar, but with some
small differences. Made those clearer by means of some comments.
Also added some comments to the middleware logic that decided
whether to extract JWK or lookup by KID.
