Controller library

This library provides a wrapper to enable Controllers interface with NATS and abstract away dealing with retrieving a Condition, execute the registered handler and publish status updates.

It covers,

• Interfacing with Jetstream, KV and dealing with keep alive sematics
• Listening for Conditions on either NATS directly or through an HTTPs endpoint provided by the Orchestator API
• Publishes the first status before executing the Controller handler method
• Invokes the Controller handler, passing it a Task object (Controllers don't know and don't care about Conditions)
• Covers up for any failures or panics in the controller Handler
• Collect trace telemetry and metrics for Conditions handled
