feat request: Allow frontend selection annotation for Ingress resource

[mike-code]

I couldn't find it in the docs, but I assume that k8s Ingress resource is always mapped to haproxy default http and https frontends.

1. I'd like to be able to pin the Ingress resource to just http or https
2. After adding raw frontend snippet and/or custom port, to be able to use Ingress resource on that port/frontend as well, without exposing it to the default http/s frontends.
