We are still going to default to 1 replica?

With this, we can now support increasing the number of replicas for a Cortex AM thus enabling HA. Please note that Alerts themselves are not gossiped between Alertmanagers. Each Ruler needs to send the alert to every Alertmanager available thus the reason why a headless service gets created when the number of replicas is more than 1.
