Control interface shall be created only for configured for it workloads

[krucod3]

Description

The basic idea here is to skip the creation of the control interface if the configuration of the workload does not contain a control interface field. Doing this will spare some green threads on Ankaios side and the creation of fifo pipes that will never be used, improving the overall performance and stability.

Goals

• A Control Interface instance shall only be created for configured workloads.

Final result
