adds subcommands for endpoints implemented in #160
mdmctl get dep-devices
mdmctl get dep-account
mdmctl get dep-profiles
mdmctl apply dep-profiles
Closes#154
* Integrate Profiles into Blueprints
* Listen for events and deploy blueprints for new enrollments
* Track enrolled status of (re-)enrolling devices and re-issue the Check-In Event under a different topic
* Added references to #149 and #110 for direction/conceptual background
* Closes#149 (largely implemented here)
* Profile service/store, API, and mdmctl management
* Group methods with their types
* Centralize error checking and remove profile ID specification on upload (unnecessary)
* Move more error checking into methods
