[JENKINS-62386] Use get latest console output option to speed up host key validation

Host key validation is taking somewhere between 8-10 minutes for me. I think this is because the EC2 console output is not updated regularly, in my tests using the AWS CLI has taken around 8 minutes for the console output to be updated after starting an instance. Using the --latest CLI option reduces the time taken to get the host key through the AWS CLI substantially.

No file or test is named. Start by locating the EC2 console-output retrieval used during host key validation, then compare its AWS CLI behavior with the reported --latest option. Done means host key validation retrieves the latest output and avoids the reported 8–10 minute delay.
