Prior to this commit, the Micrometer context-propagation project would
help propagating information from `ThreadLocal`, Reactor `Context` and
other context objects. This is already well supported for Micrometer
Observations.
In the case of Kotlin suspending functions, the processing of tasks
would not necessarily update the `ThreadLocal` when the function is
scheduled on a different thread.
This commit introduces the `PropagationContextElement` operator that
connects the `ThreadLocal`, Reactor `Context` and Coroutine `Context`
for all libraries using the "context-propagation" project.
Applications must manually use this operator in suspending functions
like so:
```
suspend fun suspendingFunction() {
return withContext(PropagationContextElement(currentCoroutineContext())) {
logger.info("Suspending function with traceId")
}
}
```
