Closes #968
This is mostly a POC at this point, since I haven't done any work to support both classic ELB's and new ALB's so that you can easily swap between both in case there are issues.
But, this does seem to work. The advantage of using ALB's is primarily that we no longer need to allocate and manage instance ports, which means multiple "web" procs can run on the same EC2 instance.
The first commit just updates the aws-sdk-go dependency, and the second includes the actual changes that switch to ALB's.
