SwaggerClient.from_url should have timeout

[guerda]

The requests in bravado can be configured to have a timeout. Unfortunately, this does not affect the from_url() method.
Would it be possible to add a time out feature in that method, too?

Best,

Maybe it's possible to insert the timeout into the request headers here:

bravado/bravado/client.py

Line 95 in f8f98c0

loader = Loader(http_client, request_headers=request_headers)

We'll need to pass a timeout argument to the result call. The best option is probably to add a timeout argument to SwaggerClient.from_url and pass it down the call chain. @guerda, would you be interested in working on a PR?
