> Support system property "ozone.scm.container.placement.classname" in ozone-site.xml.
User can specify the implementation class name as the value of the property.  Here is an example,

>  <property>
>     <name>ozone.scm.container.placement.classname</name>
>     <value>org.apache.hadoop.hdds.scm.container.placement.algorithms.SCMContainerPlacementRackAware</value>ß
>  </property>
> If this property is not set, then default org.apache.hadoop.hdds.scm.container.placement.algorithms.SCMContainerPlacementRackAware
will be used.
