Description of problem:
Install issues for 4.14 && 4.15 where we lose contact with kublet on master nodes.

4.14 is interesting as it is a minor upgrade from 4.13 and we see the install failures with a master node dropping out.

We are seeing this on a high number of failed payloads for 4.14 && 4.15. Additional recent failures
4.14.0-0.ci-2023-09-17-012321
aggregated-azure-sdn-upgrade-4.14-minor shows failures like: Passed 5 times, failed 0 times, skipped 0 times: we require at least 6 attempts to have a chance at success indicating that only 5 of the 10 runs were valid.
Checking install logs shows we have lost master-2
