> Currently if a client wants to connect to Ozone cluster we need multiple properties to
be configured in the client.
> For RPC based connection we need
> {{ozone.ksm.address}}
> {{ozone.scm.client.address}}
> and the ports if something other than default is configured.
> For REST based connection
> {{ozone.rest.servers}}
> and port if something other than default is configured.
> With the introduction of Service Discovery API the client should be able to discover
all the configurations needed for the connection. Service discovery calls will be handled
by KSM, at the client side, we only need to configure {{ozone.ksm.address}}. The client should
first connect to KSM and get all the required configurations.
