HONEYCOMB-61: Add BA broker for context data tree
With broker, context data can be accessed in a transactional
manner, same as config data
+ Renamed data-api concepts to not include DataTree
+ Renamed context related concepts to better distinguish between them
+ Now passing full ReadContext to read customizers
+ Naming context is backed by context data broker
