Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves test failures on Nokia devices by introducing a specific deviation for SSH server host certificate telemetry. As Nokia platforms do not support this telemetry, the affected test assertions in the hiba_authentication and host_certificates test suites are now conditionally executed, preventing failures on Nokia while preserving full test coverage for other compatible platforms. This enhancement improves the overall reliability and platform compatibility of the test infrastructure.

Highlights

• New Deviation Introduced: A new deviation, ssh_server_host_certificate_telemetry_unsupported, has been added to account for Nokia devices that do not support SSH server host certificate telemetry.
• Conditional Test Execution: The hiba_authentication_test.go and host_certificates_test.go files were updated to conditionally skip SSH server telemetry checks if the new deviation is active for the device under test (DUT).
• Host Certificate Version Update: The hostCertificateVersion in hiba_authentication_test.go was changed from a dynamically generated value to a fixed string constant "v1.0".

Code Review

This pull request introduces the ssh_server_host_certificate_telemetry_unsupported deviation to allow skipping SSH server host certificate telemetry checks on unsupported platforms, specifically targeting Nokia. The hiba_authentication and host_certificates tests were updated to utilize this deviation, and hostCertificateVersion was converted to a constant. Review feedback suggests broadening the documentation comments for the deviation to include all affected telemetry paths and removing an extra blank line in the proto file for consistency.
