[harkirat22]

fix proposed for #569 includes:

1. Enhancing the existing policy to only throw violation if private_endpoint is not true and master_authorized_networks_config is not used.
2. Included new policy with medium violation provided master_authorized_networks_config CIDR block has a public IP address associated.
