Kubernetes Services and Service Discovery | ClusterIP, NodePort, LoadBalancer, ExternalName

In this video we actually took a deeper look into what are Kubernetes Services and once we have created Kubernetes Services how do we actually access them or discover them from client pods.
We also looked into the Services without selectors and their use case and discussed about all the types of services, ClusterIP, NodePort, LoadBalancer and ExternalName, but actually creating them and exposing a workload
using those services.

I have also added the end screens of the videos where we started talking about Kubernetes and other one where we actually wrote a go REST API application and deployed that on Kubernetes.
