Description

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.
