Issue XD-1960: Prevent deploying modules of same type on a given stream/job when new leadership election happens
When the leadership election happens, the new deployment supervisor's container listener tries to deploy unallocated modules (via ArrivingContainerModuleRedeployer) into existing container that has the modules of the same type on a given stream/job already deployed. Currently, on a given stream/job we don't allow more than one deployment of the same module type and there by avoiding any conflicting properties for the given module type.
