The minimum allowed OS version. If not set, any version of this OS
satisfies the constraint. Format: "major.minor.patch".
Examples: "10.5.301", "9.2.1".
Only allows requests from devices with a verified Chrome OS.
Verifications includes requirements that the device is enterprise-managed,
conformant to domain policies, and the caller has permission to call
the API targeted by the request.
