Switches all SSH/SCP commands to tunnel through IAP, bypassing firewall rules (uses Google's Iam awareness service account proxy). Adds stderr suppression to commands that were leaking connection handshake details in public logs.
This PR depends on the relay harness changes to pass IAP flag to test script. The workflow will still fail until the iap tunneling permission is added to the GCP service account key -- @mgmobrien is aware of needed permish.
