Making sure that the key value is converted to a string to avoid concatenation errors

[johnroach]

SUMMARY

VMWare for certain custom attributes returns some key's as a number. This causes the vmware_inventory.py script to fail when concatenating the values to produce a group name for the VMWare inventory.
