Monitoring accuracy and latency of reported information in KCNR

[caohe]

What would you like to be added?

This issue proposes the implementation of a monitoring system to track the accuracy of the reported information in KCNR and to measure the latency in reporting this information. The following features should be added:

• Accuracy Monitoring: Implement a mechanism to compare the reported data in KCNR with the actual resource allocation on each NUMA node.

• Latency Monitoring: Measure the time taken from the moment a Pod is scheduled to the moment it's information is successfully reported to KCNR.

• Visualization: Provide a dashboard that displays accuracy and latency metrics.

Why is this needed?

KCNR is a CRD that stores topology status and resource allocation information of a node. Katalyst gathers and reports these information to KCNR. However, there are concerns about the accuracy of the reported information as well as potential delays in reporting.
