💡Allow dashboard tunnel creation and route limits simultaneously

**Describe the feature you'd like**

At the moment we can create tunnels through the Cloudflare web dashboard. But these tunnels when started with the provided token on a Kubernetes cluster has full access to everything. We can just configure in the dashboard what we want a domain to point to. That makes the Cloudflare dashboard very vulnerable from a security perspective.

I would like to be able to create a tunnel in the dashboard, but then when starting the Cloudflared container be able to specify which ips/hosts/ports should be allowed and which should be blocked.

**Describe alternatives you've considered**

Making manual tunnels using a config file. But loses the advantages of the dashboard
