Schedule api show active schedule

[johrstrom]

The schedule api is currently faulty where it only returns a struct with the name and the current start time. This issue is to build out that api to show the entire schedule as it stands with whatever events

The only question is how much business logic should be shown through the api. That is, show events and constraints both and let the user determine failure or just set some sort of flag in the struct. Saying that out loud seems to tend to the latter. That the node should hold state and expose that state through the api.
