With OpenShift Web Console Dashboards in 4.12, memory limits and requests are not overlayed

From Openshift 4.12 Webconsole Administrator->Observe->Dashboards, both CPU and Memory Usage graphs display values for available containers CPU/Memory usage cumulatively. These values should instead be overlayed. 

When clicking the `Inspect` option of the CPU/Memory Usage panel, the values are showed overlayed and not cumulatively. 

When we move the mouse over the CPU/Memory Usage graph, there is pop-up dialog that displays CPU/Memory limit & resource values, however, the Y-axis values display the total value equal to the sums of the available containers(i.e. container1 usage + container2 usage + ...). 

OCP 4.12

all the time

1. install OCP 4.12
2. Check Y-axis values for CPU Usage & Memory Usage graphs available from Administrator Webconsole-->Observe-->Dashboards

The pop-up dialog that occurs in CPU Usage & Memory Usage panel displays correct resource usage values. Thus, the values seen in Y-axis should also be overlayed.
