Fix Bug 1973: VIM Resources Type Overview issue in Dashboard

	- Charts of selected VIM Resource type will change when a different type is selected.
        - VIM resource overview shows 'No Data' content for invalid VIM account details.
	- Added tooltip in VimAccountActions for VimResourcesOverview &
	  RunningInstances
