Description

This was first mentioned under HDDS-281 by Ajay:

+1 on this. Also if we can show % of close and open containers.

It looks like HDDS-5314 didn't fully implement the open container page on the Overview page. It only implement that for each datanode on the Datanodes page.

We need to:

(1) add field openContainers to "/clusterState" endpoint first. Thought: It either needs to count the number of unique open containers from all datanodes, or there might be an existing container map structure that has all the container info (hint: check usages of ContainerInfo class. If its state is OPEN, then it should be accounted for)
(2) then display number of open containers on the Overviews page
