Event Processor SDK

[peterschwarz]

This RFC proposes extensions to the Sawtooth SDK's to support event processing. These events are emitted by the validator on block commits and can be subscribed to via client messages.

These SDK extensions propose a simplified abstraction on top of these client messages in order to provide a simple model for handling the events. This API is akin to the Transaction Handler/Transaction Processor API's.
