Support for Docker Swarm

[Nynra]

Docker Swarm is awesome when working with multiple nodes.
When using multiple nodes docker swarm is very convenient, but just as normal docker the commands can be cumbersome to type. This project looks amazing and I would very much like to use it on one of my manager nodes.

Describe the solution you'd like
Right now docker swarm is not supported and it would be awesome if some things like deploying/updating and state-monitoring can be done using this TUI (ofcourse there are also secrets, configs, networks, etc but these are used less often)

Additional context
Most commands are the same between docker swarm and normal docker. The main differences are in deploying stacks/services and monitoring commands.
