qapi/qom: Add ObjectOptions for filter-*
This adds a QAPI schema for the properties of the filter-* objects. Some parts of the interface (in particular NetfilterProperties.position) are very unusual for QAPI, but for now just describe the existing interface. net.json can't be included in qom.json because the storage daemon doesn't have it. NetFilterDirection is still required in the new object property definitions in qom.json, so move this enum to common.json.
