        # Modify an instance
        #
        # ==== Parameters
        # * instance_id<~String> - id of instance to rename
        # * params<~Hash> - depends on type of request
        #
        # ==== Returns
        # * response<~Excon::Response>:
        #   * body<~Hash>:
        #     * 'success'<~Bool>:
        # OR
        # * response<~Excon::Response>:
        #   * body<~Hash>:
        #     ????
        #     * 'expirationTime'<~Integer>: new expiration time of instance (epoch)

        #  Note: The feature of dynamically attaching or detaching storage is only
        #  supported by data centers where the KVM host version is RHEL 6.1. If the
        #  feature is not supported by the data center, you will get an exception like
        #  "Unsupported exception. Dynamic features are not supported on the KVM
        #  Host".
