Onboarding foundation changes for ItemManager

Resolved conflicting changes

1. Split ItemManager to ASDCItemManager and ItemManager
2. ItemManager provides basic capability of item without collaboration
3. AsdcItemManager provides all capabilities of item including
   collaboration which are required by onboarding
4. ItemManager can be used by other services like activity spec to
   create a basic item without collaboration features.
