Support setting dashboard entryPoints for ingressRoute resource

[abarrak]

What does this PR do?

This allows overriding entryPoints when the dashboard is to be exposed over web , or websecure.

Motivation

In certain cases, people need to expose the dashboard through web 80 or websecure 443.
It's not feasible through values.yaml as it not available, thus requires applying it manually as specified in README.

This makes it difficult to manage when used as dependency.
For example k3s auto-updating HelmChart CRD would override the configured values back to the fixed defaulttraefik.
See this.
