/// Configuration for the default UUID request ID extension which has the following behavior:
///
/// 1. Request ID is propagated using the :ref:`x-request-id
/// <config_http_conn_man_headers_x-request-id>` header.
///
/// 2. Request ID is a universally unique identifier `(UUID4)
/// <<https://en.wikipedia.org/wiki/Universally_unique_identifier#Version_4_(random>)>`_.
///
/// 3. Tracing decision (sampled, forced, etc) is set in 14th nibble of the UUID. By default this will
/// overwrite existing UUIDs received in the ``x-request-id`` header if the trace sampling decision
/// is changed. The 14th nibble of the UUID4 has been chosen because it is fixed to '4' by the
/// standard. Thus, '4' indicates a default UUID and no trace status. This nibble is swapped to:
///
/// a. '9': Sampled.
/// b. 'a': Force traced due to server-side override.
/// c. 'b': Force traced due to client-side request ID joining.
///
/// See the :ref:`x-request-id <config_http_conn_man_headers_x-request-id>` documentation for
/// more information.
