Fixed #17371 -- Made the test client more flexible

OPTIONS, PUT and DELETE requests in the test client
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Unlike GET and POST, these HTTP methods aren't implemented by web browsers.
Rather, they're used in APIs, which transfer data in various formats such as
JSON or XML. Since such requests may contain arbitrary data, Django doesn't
attempt to decode their body.
However, the test client used to build a query string for OPTIONS and DELETE
requests like for GET, and a request body for PUT requests like for POST. This
encoding was arbitrary and inconsistent with Django's behavior when it
receives the requests, so it was removed in Django 1.5.
If you were using the ``data`` parameter in an OPTIONS or a DELETE request,
you must convert it to a query string and append it to the ``path`` parameter.
If you were using the ``data`` parameter in a PUT request without a
``content_type``, you must encode your data before passing it to the test
client and set the ``content_type`` argument.
Features deprecated in 1.5
