Description

We could add option to DefaultProducer so any producer allows to defer its startup (doStart) to when the first message is being processed. The danger is that the startup logic has to be thread-safe and if there are concurrent messages then they would need to hold back until the startup is done. This is a trade-off that the user would need to accept if enabled.

But this can make it easier to let Camel startup routes even if some remote server is not available when a producer startup as part of route startup.
