NIFI-15860 Add Registered Flow ID Version Path to MDC Attributes

[exceptionfactory]

Summary

NIFI-15860 Adds registeredFlowIdentifierPath as a Logging Attribute for Process Groups, based on the presence Version Control Information associated with the current Process Group or any parent Process Groups.

The Registered Flow Identifier Path follows a structure similar to the Process Group ID Path and Process Group Name Path attributes, where each path segment corresponds to a Process Group, starting with the root Process Group.

Process Groups that are not under version control use a placeholder value of UNREGISTERED. Registered Process Groups contain both the Registered Flow Identifier and the Registered Version, separated by a colon character. A child Process Group with a parent that is registered would produce a registeredFlowIdentifierPath as follows:

/12345678-1234-1234-1234-123456789012:1.0.0/UNREGISTERED

Additional unit tests exercise the updated Logging Attributes methods.
