HP-RK API Review: Make OperationContext Containers keyed by name rather than static Uint32, to allow extension of Containers outside of the Pegasus infrastructure.  Add a destroy() method to the Container class to allow the Container itself to control memory management.  Move internal Container definitions to OperationContextInternal to keep them out of the SDK API.  Move IdentityContainer member data to a Rep class so it may be changed/extended.
