The interface has changed a little instead of allowing the client to
parse out the authorization header, it takes the request object as is
to extract the identity from it how the implementation decides.
IdentityClient#authenticate is now deprecated, in favor of
IdentityApi#getIdentity.
I am leaving the IdentityClient in place deprecated so that plugins
that use this can migrate away from it.
