Add --no-autoupdate flag for cloudflare-tunnel-remote

[alinbalutoiu]

It seems that the cloudflare-tunnel-remote helm chart is missing the --no-autoupdate flag which is added to the default image in the entrypoint looking at the image layer:

ENTRYPOINT ["cloudflared" "--no-autoupdate"]

This results in cloudflared crashing everytime there is a new update. Looking at the logs of the pods stuck in crashbackloopoff:

2023-08-31T19:45:32Z INF cloudflared has been updated version=2023.8.2
2023-08-31T19:45:32Z INF Restarting service managed by SysV...
2023-08-31T19:45:32Z INF PID of the new process is 16
2023-08-31T19:45:32Z ERR Initiating shutdown error="cloudflared has been updated to version 2023.8.2"

It seems that it restarts itself once the update is finished, but since this is a pod, Kubernetes will restart it with the same configuration and cloudflared will be stuck in the same loop forever:

$ kubectl get pods -n cloudflared
NAME                                                   READY   STATUS    RESTARTS      AGE
cloudflared-cloudflare-tunnel-remote-dbcf68f9d-m77s6   1/1     Running   2 (23s ago)   2m

With this PR, the update will be shown in the logs as a warning and the pods will no longer be stuck in crashbackloopoff:
