Runner registration does not support client certs (tls-cert-file and tls-key-file), or generic register flags
I have a GitLab server backed by client ssl cert auth.
The gitlab-runner register command supports --tls-cert-file and --tls-key-file arguments, which (tested by running manually) work. However, these are not exposed by the chart.
The configmap register-the-runner
does not support these flags, or something like a {{ .Values.runner.additionalRegistrationFlags }}
value to configure these (or other) flags. Setting envs for CI_SERVER_TLS_CERT_FILE and CI_SERVER_TLS_KEY_FILE does not work for registration either.
