2010: fix to expose correct monitoring port (#1405)

* 1399: added pod matching label in service selector

* correct fix

* 2010: fix to expose correct monitoring port

training-operator exposes 8080 per logs
2021-09-14T19:31:49.294Z	INFO	controller-runtime.metrics	metrics server is starting to listen	{"addr": ":8080"}
hence when we do local testing, it works fine
but when we expose it using make deploy then inside k8s, its not exposed

* reverting fix from other fix-branch

* now prometheus will scrape on 8080
