[Axis2] Context Hierarchy

[Eran Chinthaka]

Hi Devs,

Our Context hierarchy is as follows.
ConfigurationContext                   AxisConfiguration
           |                                                  |
ServiceGroupContext                  ServiceGroupDescription
           |                                                  |
ServiceContext                           ServiceGroupDescription
          |                                                   |
OperationContext                       ServiceDescription
         |
MessageContext                        


For consistancy and clarity, I'd like to propose to do a small name change.
   1. ConfigurationContext --> AxisContext
   2. AxisConfiguration --> AxisDescription

We do always have naming wars, hope this will not be another one :)
