[pdm-devel] [PATCH datacenter-manager] server: metric collection: include pbs nodes in top-entities

[Shan Shaji]

Applied this patch and tested the following:

- Added a backup server through the PDM UI. 
- The backup server was visible under the "Nodes with highest CPU Usage"
  panel and the "Nodes with Highest Memory usage" panel. 

Note: One small thing that i noticed is that when i added the 
backup server, it was immediately visible under the remotes 
configuration. However, on the dashboard, the backup server 
did not appear under the panels when i clicked on the dashoard 
menu. Had to refresh the browser to see the updated panels. 

So i tried adding it again and this time i didn't refresh the browser
waited for automatic refresh to happen. After the automatic refresh, 
the data was visible in the panels, so i think it's fine.
