Malcolm "plugin architecture" for "apps"

[mmguero]

In a brainstorming session here, it was suggestion that we create a Malcolm "plugin architecture" that would allow other apps to be part of Malcolm. Essentially I think you'd have something like a plugin folder where the developer of the plugin would define:

• docker image OCI URL (ie docker container name), or perhaps a complete docker-compose service that could be included in the main one
• something to tell NGINX how to point to the upstream (ie., we'd have to autogenerate some of our nginx.conf to define the upstreams and location rules)
• something to tell us how to import a link to their web app for link into to show up in dashboards or whatever
• some way to specify configuration/environment variables?

kind of a cool idea
