Description

In YARN-313, we provide CLI to refresh NMs' resources dynamically. The format of dynamic-resources.xml is something like following:

<configuration>
  <property>
    <name>yarn.resource.dynamic.node_id_1.vcores</name>
    <value>16</value>
  </property>
  <property>
    <name>yarn.resource.dynamic.node_id_1.memory</name>
    <value>1024</value>
  </property>
</configuration>

This looks too redundant from review comments of YARN-313. We should have a better, concisely format.
