This can be fully removed since port 8686 is only for the legacy kube-state-metrics stuff that's being removed.

Add a TODO here to add a --metrics-addr flag to the ansible operator and default it to 8080.
See #3440
Once we have an equivalent PR merged for ansible, we'll need to update this port to be 8080.

Since the metric is now on 8383 via the instrumented handler:

Description: Remove kubemetrics package reference logic from cmd/ansible-operator/main.go.
Remove corresponding checks from hack/tests/e2e-ansible.sh
Motivation: Now that we have handler to setup metrics on primary resources using handler.InstrumentedEnqueueRequestForObject{}, we do not separate KubeMetrics to setup metrics.
