NIFI-5279: Allow components up to 50 milliseconds to complete validation before

> Wait a bit for components to finish validation on updates

> Key: NIFI-5279
> URL: https://issues.apache.org/jira/browse/NIFI-5279
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Reporter: Mark Payne
> Assignee: Mark Payne
> Priority: Major
> Fix For: 1.7.0
>
>
> When a Processor, Reporting Task, or Controller Service is updated, it is now
> validated asynchronously. This provides a faster response time for the web
> request but can sometimes result in a component showing a "Validating..."
> state when the response is received, even though the validation logic would
> complete very quickly. When we make an update to a component, instead of
> immediately creating the DTO, which would reflect that the state is
> "validating..." we should wait up to some amount of time (say 50
> milliseconds?) for the validation to complete, before we create the response.
> This way, components whose validation completes quickly still show as Valid
> or Invalid as soon as the response comes back and only those components that
> actually take a long time to validate will show as Validating.
