31789	Add a cleaner interface for response headers	Tom Carrick	Tom Carrick	"This proposal is to replace `HttpResponse._headers` with `HttpResponse.headers` as a public interface using a variation of `django.utils.datasctructures.CaseInsensitiveMapping`.

It also includes updating tests and documentation to use this, rather than the old dict-like interface, i.e. `response.headers['Content-Type'] = 'application/json'`  `response['Content-Type'] = 'application/json'`.

The dict-like interface won't be deprecated, but will become undocumented, and tests added purely for backwards-compatibility.
