rootdir: Add cgroups and task profiles description files 



Add cgroups.json and task_profiles.json file to be places under /etc/ on
the device to describe cgroups to be mounted and task profiles that
processes can request. This adds additional layer of abstraction between
what a process wants to achieve and how system implements that request.

test: builds, boots
