Add hash operation support to Crypto service provider

Adds support for multi-step hash operations.  Only includes
protocol support for packed-c serialization at the moment.
Protobuf serialization still needs to be added.  Includes
crypto context management that can be used for any multi-
step operations such as MAC and symmetric encrypt/decrypt.
