Cleanup old TLS secrets

[benoit74]

Cert-manager is complaining about missing certificates for some existing secrets:

cert-manager/secret-for-certificate-mapper "msg"="unable to fetch certificate that owns the secret" "error"="Certificate.cert-manager.io \"<certificates.cert-manager.io>\" not found" "certificate │
│ "={"Namespace":"<certificate namespace >","Name":"<certificate name>"} "secret"={"Namespace":"<secret namespace>","Name":"<secret name>"}   

This is due to the fact that TLS secrets are not persisted in the repo and hence not cleaned-up when we remove the service and its certificate.

Secrets have to be deleted manually (todo once production is stable again / next monday hopefully)
