Default timeout for requests.Session object

[moliware]

The idea is to have a default timeout for each request you make with a session object.

Example:

>>> import requests
>>> s = requests.Session()
>>> s.timeout = 1
>>> s.get('https://httpbin.org/delay/10')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "requests/sessions.py", line 473, in get
    return self.request('GET', url, **kwargs)
  File "requests/sessions.py", line 461, in request
    resp = self.send(prep, **send_kwargs)
  File "requests/sessions.py", line 564, in send
    r = adapter.send(request, **kwargs)
  File "requests/adapters.py", line 384, in send
    raise Timeout(e, request=request)
requests.exceptions.Timeout: HTTPSConnectionPool(host='httpbin.org', port=443): Read timed out.

I came up with this PR to meet a need of a project based on requests => RedTuna/mysolr#40

Thanks!

Thanks for this!

Unfortunately, this is a feature request that comes up often but that we don't have any real interest in. See #2011 for a longer form justification. For this reason, I'm afraid that we can't accept this pull request. Thanks so much for the work though, and please do keep contributing! 🍰
