Pylint missing-timeout / W3101 is a new exception

[ross-spencer]

Pylint have introduced a new exception, W3101 which is currently in our ignore patterns. We should determine what the best course of action is, whether there is a default timeout that is reasonable for our requests, and implement it in code.

missing-timeout / W3101
Message emitted:

Missing timeout argument for method '%s' can cause your program to hang 
indefinitely

Description:

Used when a method needs a 'timeout' parameter in order to avoid waiting for a 
long time. If no timeout is specified explicitly the default value is used. 
For example for 'requests' the program will never time out (i.e. hang 
indefinitely).
