NIFI-8644: Introduced a notion of ParameterProviderDefinition

- Refactored stateless to use this when creating a dataflow so that Parameter Provider implementations can be externalized into NARs. Also updated ExtensionDiscoveringManager such that callers are able to provide a new type of class to be discovered (e.g., ParameterProvider) so that the extensions will be automatically discovered
- Put specific command-line overrides as highest precedence for parameter overrides
- Make ParameterOverrideProvider valid by allowing for dynamically added parameters
- Fixed bug in validation logic, added new system tests to verify proper handling of Required and Optional properties
- Addressed review feedback and fixed some bugs. Also added system test to verify Parameter Providers are working as expected

This closes #5113
