Cookies are treated unusually in requests. To handle them exactly as
requests does we would need to create httplib responses with headers and
pass those back. This would be a significant change that is a little
tricky. Instead use the available requests cookies handlers to merge the
cookies into the responses returned from the adapter.
Provide a way to create and preload a CookieJar that will be returned as
part of responses. We also provide the dict interface that requests
does. We don't really have a lot of choice here as these interfaces are
supported by the cookie apis and we would need to actively work around
things to remove that interface.
