Please describe the new behavior that that will improve Egeria

A new build warning has appreared since the last set of dependabot updates indicating that the FileAlterationObserver class has been deprecated in Apache Common.

.../egeria/open-metadata-implementation/frameworks/open-integration-framework/src/main/java/org/odpi/openmetadata/frameworks/integration/filelistener/FilesListenerManager.java:89: warning: [deprecation] FileAlterationObserver(String) in FileAlterationObserver has been deprecated
        FileAlterationObserver observer = new FileAlterationObserver(fileToMonitor.getAbsolutePath());

The FileAlterationObserver is used in the FilesListenerManager of the Open Integration Framework (OIF) to make it easy for integraiton connectors to monitor the file system.

The recommended replacement is java.nio.file.WatchService. This has a huge advantage in that is does not require an external dependency.

Ideally we want to swap in the new class without changing the FileListenerManager interface.
