[WINC-1971] [ote] Fix proxy test timing issues

[rrasouli]

Fix 3 failing proxy tests by addressing timing issues and removing dependency on QE-specific cluster setup:

OCP-90290: Remove trusted CA - WMCO restart timeout
OCP-90289: Remove proxy vars - WMCO restart timeout
OCP-68320: Certificate propagation timeout and QE dependency

Changes

Timing fixes (ote/test/e2e/utils.go)

• checkWMCORestarted(): Return (false, nil) on wait.ErrWaitTimeout instead of error
  • Some proxy changes don't trigger WMCO restart, which is valid behavior
  • Propagate other errors with %w for proper error handling
• checkUserCertificatesOnNodes(): Increase timeout from 5min to 10min
  • Certificate propagation on proxy clusters can be slower

OCP-68320 test fix (ote/test/e2e/proxy.go)

• Remove dependency on QE-specific Installer-QE-CA certificate
  • This certificate only exists in QE cluster setups, not in CI-provisioned clusters
  • Test was failing immediately on first verification step (expected 1 cert, found 0)
• Test now validates certificate sync using only the self-signed certificate it creates
  • Verify cert sync after initial add (count = 1)
  • Verify cert sync after rotation (count = 1)
  • Verify cert removal (count = 0)
• This fully tests the certificate propagation mechanism (user-ca-bundle ConfigMap → Windows nodes) without requiring QE-specific setup

Pipeline controller notification
This repo is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. To trigger manually all jobs from second stage use /pipeline required command.

📝 Walkthrough

Walkthrough

The end-to-end utilities now treat a six-minute WMCO restart timeout as a non-fatal result and log that no restart occurred. Certificate propagation polling now waits up to ten minutes. The related timeout assertion message reports the ten-minute deadline.

Merge Risk: 🟡 Moderate · up to 1c861

The proxy E2E test can report a normal no-restart outcome when WMCO timestamp queries fail, potentially skipping restart-dependent validation during API or permission failures. Preserve non-timeout errors before merge.

propagate errors from getWMCOTimestamp instead of converting them to a
successful nil error; treat only the wait.Interrupted timeout as the expected
no-restart result, and return all other errors so callers retain API or
