Feature: ArrayNode#set(int index, type value)

[Tarekk Mohamed Abdalla]

ArrayNode currently have add and insert function of all types (int, double, etc) but the set function only have JsonNode variant.

My feature request is to add set methods for other types 

 ArrayNode arr = getNewArrayNode();

 arr.add("a");

 arr.insert(0, "b");

 arr.set(1, "c"); // <------- Missing

What do you think about this change?

P.S I have an issue with this feature request on GitHub #3154
