go-redis provides 4 different types of protocols to connect to Redis

• Normal standalone: https://redis.uptrace.dev/guide/server.html#connecting-to-redis-server
• Cluster: https://redis.uptrace.dev/guide/cluster.html
• Ring: https://redis.uptrace.dev/guide/ring.html

Similarly, Redigo provides a single method:

• Conn: https://pkg.go.dev/github.com/gomodule/redigo/redis#Conn

And as we only use Do method of both the clients. Hence, in order to support these different types of connections in each client, abstracting the required method is the only feasible option

[Shivam010]

This removes the direct dependency on the corresponding libraries' clients for obtaining a connection

@Shivam010 +1 for solution, this solution will work with all types of clients
