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.
