asset/manifests: update status of Infrastructure

This updates the `Infrastructure.config.openshift.io` object to catch up with [1].

Machine Config Operator uses the `APIServerURL` to point the kubelet on machines to apiserver, and `EtcdDiscoveryDomain` to setup the etcd
members to bootstrap the etcd cluster using dns discovery [2].

This is required as Machine Config Operator currently uses the `cluster-config-v1` to creates these values and as `cluster-config-v1` is getting deprecated [3], Machine Config Operator will move to
using the status of `Infrastructure.config.openshift.io` for sourcing that information.
