[Docker] Every container should run in the same docker network for a single execution

[kminehart]

Requirements:

• When the pipeline starts, a docker network should be created.
• The name of the docker network should be prefixed with a known string (like shipwright-) and suffixed with a random string to avoid name collision.
• Every container created in the pipeline should be assigned to the created network.
• Every container created in the pipeline should be referrable by its name.
• When the pipeline ends, the network should be deleted.
