The context information from the provided span is used to build the traceparent header that will be propagated to the MySQL server. For particulars regarding the header creation, refer to [1]. This method assumes version 0 of the W3C specification. Args: span (opentelemetry.trace.span.Span): current span in trace. Returns: traceparent_header (str): HTTP header field that identifies requests in a tracing system.

The trace context is propagated via query attributes. The `traceparent` header from W3C specification [1] is used, in this sense, the attribute name is `traceparent` (is RESERVED, avoid using it), and its value is built as per instructed in [1]. If opentelemetry API/SDK is unavailable or there is no recording span, trace context propagation is skipped.
