Disabling cache doesn't work with requests_futures

[MaxBareiss]

When I use the requests_cache library with the requests_futures library, it works great. However, when I try to make a request without using the cache:

with requests_cache.disabled():
    rq = session.get(url)

it doesn't work:

rq.result().from_cache
True

Here's what's happening:

• requests_cache.install_cache() patches out requests.Session with requests_cache.CachedSession
• When you create a FuturesSession object, that gets created as a subclass of CachedSession instead of Session
• requests_cache.disabled() will undo the session patch, but that won't affect your existing session object

Instead, use with session.cache_disabled(). And when using requests-cache with any other library that modifies requests.Session, it's going to be a lot easier to use CachedSession directly instead of using the global patching method (install_cache()). There are some related examples in the docs here.

It looks like you can also pass a session object to FutureRequest, so this would work too:

session = FutureSession(session=CachedSession())

Also, this may not be helpful if you have a specific reason for using requests-futures, but if you want async HTTP requests, using aiohttp is a much better solution.

I'll leave this issue open as a reminder to add an example to the docs specifically for requests-futures.
