[NFR] Implement getPut()

[fdjean]

Hello,

$this->request->getPut()

Similar to getPost() or getQuery()

Thx

If your put data is in the form of query string:

$put = array();
parse_str($this->request->getRawBody() , $put);

If your put data is JSON, use json_decode($this->request->getRawBody()) instead
