builds

v3 introduces the new 'build' data type, for managing groups of devices.

New crud endpoints for:

• listing, creating builds
• starting, completing a build; clearing start or completed attributes
• adding, removing, updating users in builds
• adding, removing, updating devices in builds
• adding, removing, updating racks in builds

Modify permission-checking algorithms for racks, devices to also consider user-build-role entries and device-build, rack-build relationships.

as per discussion on ~thermal, it would be useful to support arbitrary settings at the build level (e.g. max_burnin_time would be more appropriate stored on builds than on users).
