/**
 * Pushes the given span onto the {@link #currentSpanStackThreadLocal} stack. If the stack is null it will create a new one. Also pushes the span info into the logging
 * {@link org.slf4j.MDC} so it is available there.

 * If you're trying to complete the overall request's span you should be calling {@link #completeRequestSpan()} instead. If there are 0 or 1 spans on the stack then
 * this method will log an error and do nothing.
