Talk about the portainer API

[unglaublicherdude]

Hi,

in slides/swarm/gui.md you mention portainer and also deploy the tool into a swarm.

We do use the portainer API and its feature to deploy stacks via an API - a feature that is missing in the docker api. Maybe this would we worth mentioning. The API of portainer is also behind an authentication and you can deploy on multiple swarms (when using the portainer-agent) with it.

Cheers,
Matthias
