Option to get access to multiple docker instanzes

[Nanabell]

At the moment i would recommend to launch an agent inside each individual Docker System and connect them to one central Agent Orchestrator.

Allowing a single agent to control multiple Docker hosts would require a complete re-write of the logic of both the agent and orchestrator, thus i'd like to push this back for now as its not strictly necessary right now
