> The setting *ozone.scm.block.client.address* allows extra flexibility but it is set to
the *ozone.scm.client.address* all the time when we deploy the cluster.
> Currently, KSM will fail to startup if *ozone.scm.block.client.address* is not configured.
This JIRA suggests that we use *ozone.scm.client.address* as the default for the *ozone.scm.block.client.address*,
so we don't have to explicitly configure *ozone.scm.block.client.address*.
> Change involves modifying *getScmAddressForBlockClients* and the passing the default
parameter to *getHostNameFromConfigKeys* and *getPortNumberFromConfigKeys*
