CLOUDSTACK-2624. Support ModifyInstanceAttribute API in AWSAPI.
2 AWS instance attributes will be supported, 'InstanceType' and 'UserData'
As per AWS EC2, to modify both the attributes, the instance must be stopped. If not throw 'IncorrectInstanceState' error
This is observed in the awsapi.log for all Describe* EC2 commands when the response object returned by CS has no elements. But with EC2DescribeImages command it is always observed. This is because every time DescribeImage is fired, we call CS listTemplates command multiple times, each time setting a different value for the templateFilter parameter (e.g. featured, executable, community etc.). And for some of these CS calls made we obtain am empty response and hence the message in the logs.
