NIFI-13706 Handle Exceptions Fetching Parameters on Startup

[exceptionfactory]

Summary

NIFI-13706 Updates the flow synchronization process to catch exceptions when fetching Parameters from Parameter Providers.

The framework logs a warning when catching exceptions from a Parameter Provider, and already handles logging warnings when a Parameter Provider does not return values for a configured Parameter.

This change in the startup process allows NiFi to start even when a Parameter Provider has configuration or connectivity issues. Missing Parameter values may result in flow configuration problems, which an authorized user can correct after fixing the referenced Parameter Provider.

+1 looks good and verified the behavior, this is helpful for allowing NiFi to continue to start even when failing to fetch parameters, thanks!
