[#PETALSCDK-90] No response to the service consumer if the message exchange is rejected by processors - Petals Link JIRA

Description:

If no more message exchange processors is available or no thread is available to execute a message exchange processor, no response is sent to the service consumer. The service consumer will get a time-out as error, that is not the real error.

Depends

This issue depends on:
~~PETALSCDK-88~~ StackOverflowError occurs when the JBI message processor thread pool is exhausted
~~PETALSCDK-123~~ Rework the Acceptor/Processor thread pools

This issue blocks:
PETALSDISTRIB-146 Reliability aka delivery guarantees for consumer-provider communication
~~PETALSCDK-135~~ Do not drop messages when there is no thread for processors available
