Attach the initial patch.
Hi [~xyao], do we have to move update metrics logic into other handler that you mentioned
before? I have done the remaining work for scm metrics. Thanks for the review when you get
a chance.

> We should aggregate the metrics from all the reports of different datanodes in addition
to the last report. This way, we can get a global view of the container I/Os over the ozone
cluster. This is a follow up work of HDFS-11468.
