Energy and Water GBU

Description (Required):

OCI Data Science Jobs show useful resource metrics plots, including CPU utilization, memory utilization, etc. By default, these plots show the most recent hour. However, when viewing a completed Job, the most recent hour contains no data.

Instead, the default the start and end date of the Job resources metrics plots should be the start and end time of the Job run. A Job knows it's start time (and end time if the Job has completed), so it should be possible to default the start and end times of the plots to match.
