NIFI-13813 Refactored NiFi Runtime Property Loading (#9322)
- Refactored NiFi Runtime class to read application properties for NAR loading
and then load application properties using Framework NAR
- Removed bootstrap Class Loader from runtime initialization
- Removed nifi-properties-loader from nifi-bootstrap

> The {{org.apache.nifi.NiFi}} class for launching the system uses the
> bootstrap Class Loader and reflection to load {{NiFiProperties}}, which
> introduces a tight and unclear coupling between the bootstrap process and the
> runtime application. With recent refactoring of {{nifi-bootstrap}}, this
> dependency on {{nifi-properties-loader}} in the bootstrap library directory
> should not be required.
> Instead, the runtime {{NiFi}} class can read the initial application
> properties for loading NAR modules, and then use the Framework NAR, which
> includes {{nifi-properties-loader}} to run standard loading operations. This
> approach removes the unclear coupling to the bootstrap class loader.
> In addition to these changes, the structure of the {{NiFi}} class should be
> refactored so that specific operations like initializing the JUL to SLF4J
> Bridge and setting the uncaught exception handler occur before other
> operations.
