Logging: consider using "awaiting" instead of "receiving" until a message is actually received

**User story**
As a citrus newbie, I would prefer the logs to say things like "**Awaiting** JMS message on destination...." or "**Awaiting** message from ..." instead of "Receiving JMS message on destination" and "Receiving message from..:" as long as there is not actually a message received, so that the ongoings are easier to comprehend. "Receiving" can easily be mistaken for... "receiving" 😏
Might also apply to other log messages.

Synonyms: Awaiting, expecting, anticipating, ...
