Improve stanctl down behavior

We used stanctl down and rebooted. After system start gateway-controller and gateway pods were running.

Then executed stanctl down again and got the following error:

root@instanak3s1:~# stanctl down Do you want to shut down the Instana cluster? : Yes ⣿ Switching backend to maintenance mode [2s] ✕ Error: an error occurred while rolling back the release. original upgrade error: cannot patch "instana-core-selfsigned-ca" with kind Certificate: Internal error occurred: failed calling webhook "webhook.cert-manager.io": failed to call webhook: Post "https://cert-manager-webhook.cert-manager.svc:443/validate?timeout=30s": no endpoints available for service "cert-manager-webhook" && cannot patch "instana-core-selfsigned-issuer" with kind Issuer: Internal error occurred: failed calling webhook "webhook.cert-manager.io": failed to call webhook: Post "https://cert-manager-webhook.cert-manager.svc:443/validate?timeout=30s": no endpoints available for service "cert-manager-webhook": cannot patch "instana-core-selfsigned-ca" with kind Certificate: Internal error occurred: failed calling webhook "webhook.cert-manager.io": failed to call webhook: Post "https://cert-manager-webhook.cert-manager.svc:443/validate?timeout=30s": no endpoints available for service "cert-manager-webhook" && cannot patch "instana-core-selfsigned-issuer" with kind Issuer: Internal error occurred: failed calling webhook "webhook.cert-manager.io": failed to call webhook: Post "https://cert-manager-webhook.cert-manager.svc:443/validate?timeout=30s": no endpoints available for service "cert-manager-webhook"

According to IBM case feedback, for now this is working as designed. In future, better handling will be needed to avoid confusion for the Instana user.
