Wildcard domains

[alex-bezek]

Description

The k8s ingress spec specifies that it does support wildcard hostnames https://kubernetes.io/docs/concepts/services-networking/ingress/#hostname-wildcards
For other ingress controllers which are simply proxy servers, they can set up rules to handle wildcard hosts and leave the dns up to the user. With ngrok, a matcher rule doesn't do anything if an edge isn't setup with an actual host with dns routing to it, so we'll need to setup an edge.

Currently if you try to use a wildcard, you get this error

2023-02-14T16:57:35Z	ERROR	controllers.ingress	Failed to sync ingress to store	{"error": "Domain.ingress.k8s.ngrok.com \"*-bezek-hello-world-ingress-ngrok-io\" is invalid: metadata.name: Invalid value: \"*-bezek-hello-world-ingress-ngrok-io\": a lowercase RFC 1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')"}

Use Case

Allow the utilization of wildcard domains
