Filter that makes form encoded data available through
the ServletRequest.getParameter*() family of methods during HTTP PUT
or PATCH requests.
The Servlet spec requires form data to be available for HTTP POST but
not for HTTP PUT or PATCH requests. This filter intercepts HTTP PUT and PATCH
requests where content type is 'application/x-www-form-urlencoded',
reads form encoded content from the body of the request, and wraps the ServletRequest
in order to make the form data available as request parameters just like
it is for HTTP POST requests.
