By default `.get()` will return `None` on a key that doesn't exist. This
causes a `TypeError` in the `for` loop a few lines down. This change simply

- removed import of sys module.
- HAS_BOTO constant to check if import was successful.
- trigger a failure when import fails.
- removed unnecessary imports.
Make use of improved connect_to_aws that throws an exception
if a region can't be connected to (e.g. eu-central-1 requires

Add us-gov-west-1 to ec2_ami_search to match documentation!
