Integrate discovery into crypto service provider

Integrates the discovery provider into the crypto provider to
support common discovery operations.  Will initially be used
to discover the max_payload value to allow a client to
use multi-step crypto operations where prior knowledge of
the max_payload size is needed.  This commit also includes
service level tests for discovery.
