For future readers who might find this post the issue is that the Google Cloud Logging and Monitoring Agent scripts require a PTY terminal for reasons I have been unable to asertain.
To fix this issue simply add "ssh_pty": true It seems that the interactive nature of the SSH connection unblocks some kind of HTTPS error inside of Yum. If anyone from Packer or Google would like to explore this further it would be highly interesting to know the details!
