Add a vcloud-identify-vm utility

vcloud providers seem to have a problem identifying virtual machines by
name, they prefer VM UUIDs and Org IDs.

This helper will search across all container names and vm names and show
all matching ones in a way that providers can use to uniquely identify a
VM even in the case where there are many similarly named ones.
