Fix Bug 2296: Newly Created Ns should come first in NG-UI

	- Sorted the list using created Date in descending order
        - Incorrect Information in "Expires in " section of Admin user :
	  Changed it to N/A
	- VIM Resource Overview: RAM Value should be rounded off :
	  Rounded off the value to 2 decimal points
	- Fixed the key issue in topology
