Description

This Jira is a follow up to NIFI-950. The new asynchronous validation introduces a new state VALIDATING. This VALIDATING state will be entered following any modifications (create, update) to the component (Processor, Controller Service, Reporting Task). All component validation is done in the background on a recurring interval. When obtaining the current state, we will return the last known state unless it is VALIDATING as a result of a modification.
