Begin building controlling API to facilitate control of agents

Begin building the controlling API in MiNiFi C++. This API will evolve and likely have public and private elements. As development progresses we may want more capabilities.

What I want to create as a straw man will be basic control and metrics gathering
– Start
– Stop
– Pause
– Gather metrics

• • Throughput of of flow components
  • Execution time ( run time minus sleep time )
  • Memory consumption

– Drain repositories
– Switch repository types.

Better employ update listener within this controlling API
