List of changes:

1. Due to this update, any uses of the backtraces feature have been removed.
2. Due to this update, new is now explicitly called to create Binary instance from an inner value.
3. Due to this update, newly exposed module is used to access the update_staking function directly.
4. Due to this update, calls to mock_info has been replaced with message_info.
5. Due to non_exhaustive attribute, the Delegation struct is no longer accessible from the outside of the crate where it defined. So StdDelegation struct was created as the copy of the cosmwasm Delegation to be used instead.
6. Due to deprecation, the uses of the data field have been replaced with msg_responses. Since msg_responses contains protobuf-encoded messages, the JSON deserialization methods have been replaced by decode_message_response with corresponding replacement of the response types: MsgIbcTransferResponse for MsgTransferResponse and MsgSubmitTxResponse for MsgSubmitTxResponse
