LPS-34571 formatter, javadoc, and props

I updated the javadoc formatter to handle deriving the proper service-help property name from its own class name.

For example, it was looking for d-d-l-record-set-service-help (instead of ddl-record-set-service-help for DDLRecordSetServiceImpl.

I've updated each of the service impls, summarizing the methods they provide. Some things to note...
- The method summaries can differ from LSI to SI because the SI often has less variety.
- The class descriptions for the SI's mentions permission checking--"Its methods include permission checks."
- I updated *ServiceImpl's that had the old pattern (e.g., "The implementation of ...") with this new pattern (i.e., "Provides the local service for <method summary> ...").

Hope you like it. Let me know if you have any suggestions. Thanks.
