Add support for Swarm Mode

[jtyr]

It would be nice to monitor containers across all Swarm Mode cluster.

Do you have a developer guides? I can try it.

I wrote the output for node, service and task in a docker swarm cluster. But I have interesting question. How I should get Resource usage for tasks and their containers from remove nodes? Did anyone has ideas?

I don't see a way forward with swarm support that doesn't require a stats forwarder/proxy deployed to each node in the cluster

Ok. But may be to add toggle switch to swarm mode, which displayed structure of the swarm cluster, if swarm enabled on this docker and this docker is a manager swarm. By example:

node_1
| +--service_1
|     +---task_1_1 | health_check
|     +---task_1_2 | health_check
| +__service_2
|     +---task_2_1 | health_check
|     +---task_2_2 | health_check
|node_2
 +--service_1
      +---task_1_1 | health_check

a way would be to run it as a global service, still a bit complex and a totally new application

I implemented swarm mode in ctop in my fork, but me yet need add some optimizations.
