Title: [aws|compute] Update API version and support new DescribeInstanceStatus format.

Opening a PR for this because I'm not sure what the protocol is for the DescribeInstanceStatus body changing. I'm probably missing something obvious from the past but I couldn't immediately find a case where an AWS parser changed due to a breaking change in response.

In this case, `systemStatus` and `instanceStatus` items were added and `eventsSet` changed to just a single `event`, according to the sample [here](http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeInstanceStatus.html). I also used the sample to verify the parser.

The current format was made public in fog 1.1.2 with the initial implementation of the DescribeInstanceStatus request and parser.

Halp?
