Enhance toString methods in factory classes

The factory classes in policy-endpoints have toString() methods that
return "[]" for their list contents.  Updated the code to provide a list
of the keys rather than just an empty list.
Also replaced some toString() methods with lombok.
Also replace StringBuilder with concatenation in some cases.
