Merge pull request #26783 from a-robinson/newlogs

Automatic merge from submit-queue

Add collection of the new glbc and cluster-autoscaler logs

I've incremented the version numbers by 2 to avoid conflicting with #26652. I'll make sure the potential conflict between the images gets resolved reasonably.
