Integration with SLF4J MDC.
Add MDCContext to the coroutine context so that the SLF4J MDC context is captured and passed into the coroutine.
MDC.put("kotlin", "rocks") // put a value into the MDC context
launch(MDCContext()) {
logger.info { "..." } // the MDC context will contain the mapping here
}
