Title: fix get_all_instance_status() documentation

[DescribeInstanceStatus](http://docs.aws.amazon.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeInstanceStatus.html) actually returns status of all running instances, not just the instances scheduled for maintenance.

Also updated the return type to be more accurate.
