The peer CLI currently attempts to print the error status returned by
the orderer's Deliver gRPC method.  However, the log statement
inappropriately uses the '%T' modifier, and prints the type of the
status, not the actual status code inside it.  Consequently, all deliver
errors read the same uninformative error message:

    Got Status:*orderer.DeliverResponse_Status

This CR fixes this log statement to include the status code instead, and
additionally enhances the other error messages with pertitent
information.
