Merged BRANCHES/DEV/V4.1-BUG-FIX to HEAD

47670: ALF-18245 - BM-0013: Soak: Run 06: Search population of ScriptNode is expensive
          - Optimizations to improve the performance of the repository when retrieving the populating data needed for Share Search results
          - Additional service method to PersonService to allow retrieval of a person or null in a single operation - rather than exists() followed get()
          - Improvements to generate of full name strings for a Person - only retrieve minimum needed properties rather than allprops from cm:person
          - Improvements to generation of DisplayPath to avoid multiple permission checks
