Integration into openSenseMap platform

[noerw]

I have a two-part integration in mind, in order to avoid letting users run the tool themselves, but provide a central service within the openSenseMap platform.
This would solve a long requested feature (sensebox/openSenseMap-API#53)

• add healthcheck configuration to Box schema, so users can set their healthchecks within openSenseMap, only available with authentication. This config could be set up in the oSeM frontend.

• add a command osem_notify watch all --db, which checks all boxes from the database using the protected box.healthchecks config. This requires a MongoDB driver. This could run centrally in a Docker container.

• (maybe): add a osem_notify login command, so the central configuration could be used without admin access. osem_notify * all would fetch all boxes of the logged in user.

@mpfeil: is this something you guys would be interested in?

This is definitely something for us. I have started a private project some time ago but haven't finished it.

We already discussed this feature yesterday and had some ideas too. Maybe @robarto can write down his ideas.
