+ * A converter to convert Union type to avro
+ * Here it will try all the possible converters for one type, for example,
to convert an int value, it will try all Number converters
+ * until meet the first workable one.
+ * So a known bug here is there's no guarantee on preserving precision from
Json to Avro type as the exact type information is clear from JsonElement
+ * We're doing this since there is no way to determine what exact type it is
for a JsonElement
