Handle EC2 instances with multiple network interfaces (#4766)

Browse source 
Currently instances with multiple ENI's can't be started or stopped
because sourceDestCheck is a per-interface attribute, but we use the
boto global access to it (which only works when there's a single ENI).

This patch handles multiple ENI's and applies the sourcedestcheck across
all interfaces the same way.

Fixes #3234
