Title: Added end attribute - The time when the Reserved Instance expires.

AWS::EC2::ReservedInstances was missing support for the 'end' attribute described in the REST API:

http://docs.aws.amazon.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeReservedInstances.html

I've added in that attribute.
