Allow customization of one-click Kubernetes Runner
Zendesk: https://gitlab.zendesk.com/agent/tickets/103374
At the moment the one-click installers work well, unless you have some situation that requires customized Runner settings. For example, this customer has a self-signed certificate for GitLab so the Runner couldn't connect. This means there's no easy way to customize this value and make the one-click installer work.
It would be nice if there was a way to specify configuration or environment variables or something to customize the runner installation.
