Give full explanation of sample policy JSON syntax

[BrianSipos]

• Some form of schema is necessary, CDDL or JSON-schema.

• Need to define the exact parameter names and value types for each SC ID.

• Expansions from earlier ION processing, including:

  • Deprecated the policyrule.filter.sc_id field as it is redundant with policyrule.spec.sc_id field.
  • Allow native number inputs for integer or decoding from text (allows 0x... hex inputs now also) with backward compatibility.
  • Allow native boolean inputs with backward compatibility.
  • Allow more compact policyrule.spec.sc_parms as an object with key-value pairs with backward compatibility to old array-of-pairs form.
