Modify the AppResponse struct to have the store name (#183)

* Need to change the AppResponse struct to have the store name and state requests separately to support multiple state stores support in Dapr.

This is needed to support this requirement : dapr/dapr#636

* Putting the state in a separate struct

* Reverting the last commit - and keeping the things simple, just adding the storeName in the struct
