Following items are fixed.
1) The UI displays all the VMs of the 2 vrouters in the path. Ideally, we should only display the 2 VMs that are in the path.
2) The VM display goes beyond the extreme right of the display area. We cannot easily use the links or Vms that roll of the right in this way
3) Clear highlightling elements.
4) Removing 'Reverse Map Flow' from 'Search Flows'. Can add back if required.
