buffet: Adding GCD command definition schema - phase 1.

Initial implementation of GCD command definition schema
and parsing command definition provided as JSON.

This change introduces the class hierarchy to describe
parameter type description (ParamType-derived classes),
parameter values (ParamValue-derived classes), constraints,
and general object schema which is a collection of
parameter definition for an object which corresponds
almost directly into a GCD command definition.

Object definition parsing from JSON is implemented
as well as validation of parameter values with rich
error reporting.

This is a basis for future command definition implementation
and device draft definition for GCD devices.
