CI: Conformance Ginkgo calls cilium-dbg during upgrade tests on Cilium versions that don't support it #29195
Description
CI failure
Observed in https://github.com/cilium/cilium/actions/runs/6878246033/job/18707557137#step:16:392
Fetching command output from pods [cilium-7pvbx cilium-bv9gd]
cmd: kubectl exec -n kube-system cilium-7pvbx -c cilium-agent -- cilium-dbg endpoint list
Exitcode: 1
Err: exit status 1
Stdout:
Stderr:
error: Internal error occurred: error executing command in container: failed to exec in container: failed to start exec "c9d4c3fe67af8d1065018796128991b7fd3ebcfd931f67f50a4de3952b8671b5": OCI runtime exec failed: exec failed: unable to start container process: exec: "cilium-dbg": executable file not found in $PATH: unknown
This happens during Tests upgrade and downgrade from a Cilium stable image to master, i.e. we deploy Cilium v1.14 and if that has any errors, we then call cilium-dbg endpoint list, which will not work against Cilium v1.14
Note: This does not cause CI to fail, so this is not a flake. It's a bug in our CI, but it doesn't make tests fail.
