Search all resource pools when looking for a vic vApp (vmware#7823)

If a cluster only has vApp(s) installed then there will only be
a single resource pool -- since there is only one pool vic-machine
ls assumes that DRS is disabled and doesn't look for a vApp.

This change will now search all resource pools for a vic
vApp.

Fixes vmware#7800
