uk.gov.hmrc.play.bootstrap.dispatchers

This provides an ExecutorService which copies MDC to the next execution.

This can be enabled with.

 pekko.actor.default-dispatcher {
   executor = "uk.gov.hmrc.play.bootstrap.dispatchers.MDCPropagatingExecutorServiceConfigurator"
 }

This provides an ExecutionContext which copies MDC data over in prepare(). Since prepare() is implicitly called by Promise#onComplete, MDC data will not be lost on many async boundaries. It may still be required to explicitly call prepare() in some scenarios (e.g. with pekko)

This can be enabled with.

 pekko.actor.default-dispatcher {
   type = "uk.gov.hmrc.play.bootstrap.dispatchers.MdcPropagatingDispatcherConfigurator"
 }

propagates the logback MDC in future callbacks
