re-did the folder structure for the API. The client still lives in the server
packages, but will be gradually moved into api/client to remove coupling and make the APIs clearer.
Add more logic to the way code is organized.
/pkg -- library code not directly connected to micromdm
/mdm -- packages meant for the services devices interract with. The MDM protocol.
/dep -- DEP API and related packages.
/platform -- Core APIs the server provides. Commands API, Devices API, queue, pubsub etc.
/workflow -- Packages/API that build on top of platform. Today that's the webhook package.
Depending on what ends up here, the workflow folder might become its own repository.
For #248
Added a User DB similar to the Device DB.
The user specification be added with the API/mdmctl commands and then referenced with a blueprint.
If added to the blueprint, the user will be installed as an administrator during the AccountConfiguration step.
