Add query parameter converters for complex types
* Add converter for URL query parameters of type map[string][]string * Add converter for URL query parameters of type time.Time * Added function to allocate and configure schema.Decoder for API use * Updated API handlers to leverage new converters, and correct handler code for filter type An encoding example for a client using filters: v := map[string][]string{ "dangling": {"true"}, } payload, err := jsoniter.MarshalToString(v) if err != nil { panic(err) } payload = "?filters=" + url.QueryEscape(payload) Signed-off-by: Jhon Honce <jhonce@redhat.com>
