XD-1760 Enabling Short Circuiting

Now checking deployment property values and setting the "shortCircuitAllowed"
producer property if the following conditions are satisfied:
1. producer module is not partitioning
2. producer module's count is 0
3. next module's count is 0
4. both producer module and next module have the same criteria (both can be null)

Added "shortCircuiting" tests to AbstractDistributedTransportSingleNodeStreamDeploymentIntegrationTests

RabbitSingleNodeStreamDeploymentIntegrationTests and RedisSingleNodeStreamDeploymentIntegrationTests
now both extends from AbstractDistributedTransportSingleNodeStreamDeploymentIntegrationTests
