What this PR does / why we need it:
This PR fixes an issue where experiments running SSM by tag sometimes report misleading IAM permission errors. The root cause we speculate is the implementation of DescribeInstanceInformation which do not handle pagination. By default the DescribeInstanceInfromation has limited result if the target instance resides on a subsequent page, it won’t be found in the first API response—resulting in an erroneous permission error message or so.
The fix updates the code to use the DescribeInstanceInformationPages to iterate through all pages and correctly aggregate instance information.
