Need to surface Job peak resource value(s) to job detail page so that user (admin) can easily know the job's max resource usage in a glance.

What would you like to be added:
Show peak resource used so far, so user have a chance to know if over reserved resource.

Why is this needed:
Sometime, user may apply 64G memory, but actually it's used only 4G. It wastes resource. With this feature, user has a chance aware of this, and user or admin can take action base on this information.

Taking MII deployment as an example, the memory usage is always a bottleneck. New Jobs are not able to perform because previous jobs used too much memories. Admin would like to know which jobs used too much resources.

Without this feature, how does the current module work：
User has to open metric table, and monitor it.
