Parse form

[muhammednagy]

We need to be able to parse the path parameters if the request is Get.
we need to be able to parse the path parameters AND the body if POST and be able to decode it to a struct.
if a struct is not provided then parse to a map.
It should be able to detect from the header the body type and if it's a JSON then it should parse the json
If XML then parse it as XML.
