Add monitoring and alerting manager to the existing Bassa kubernetes cluster

[kmehant]

Why

If Bassa is used by a large scale community, then there is always a need for a monitoring and alerting system integrated to the K8s cluster which will help them to know important information regarding various elements in the deployment infra.

Solution

I wish to use Prometheus over others because of the richer data model, inbuilt notifications feature, and higher uptime. We can deploy Prometheus, alerting manager, exporters, and Grafana on the K8s cluster to achieve this.
