oVirt dynamic inventory script
=================================
Generates dynamic inventory file for oVirt.
Script will return following attributes for each virtual machine:
 - id
 - name
 - host
 - cluster
 - status
 - description
 - fqdn
 - os_type
 - template
 - tags
 - statistics
 - devices
When run in --list mode, virtual machines are grouped by the following categories:
 - cluster
 - tag
 - status
 Note: If there is some virtual machine which has has more tags it will be in both tag
       records.
Examples:
  # Execute update of system on webserver virtual machine:
    $ ansible -i contrib/inventory/ovirt4.py webserver -m yum -a "name=* state=latest"
  # Get webserver virtual machine information:
    $ contrib/inventory/ovirt4.py --host webserver
