assert_json_requests_mock() helper

[jedie]

I need a way to check JSON data in requests made in views. I didn't find something in requests-mock. So i implement a simple function to check the mock.request_history

Usage looks like this:

with requests_mock.mock() as m:
    m.post('http://test.tld', text='resp')
    requests.post('http://test.tld', json={'foo': 'bar'}) # maybe this is made deeper e.g.: in a view

assert_json_requests_mock(mock=m, data=[{
    'request': 'POST http://test.tld/',
    'json': {'foo': 'bar'},
}])

The code is here: https://github.com/boxine/bx_py_utils/blob/master/bx_py_utils/test_utils/requests_mock_assertion.py

More examples are here: https://github.com/boxine/bx_py_utils/blob/master/bx_py_utils_tests/tests/test_requests_mock_assertion.py

Maybe this is useful for other users? Any interests to include this into requests-mock? Then i can try to create a pull request.
