Title: Optimalization of get*Data* methods.

- loops through members in ServiceManagerBlImpl get*Data* methodes removed
- added 4 new getRequiredAttributes to AttributesManagerImpl which take
list of members. They return map of member as a key and list of their
attributes as value.
- added new getRequiredAttributes which takes list of members, it calls
the 4 new getRequiredAttributes methods and combines their output into
one hashMap.
