I want a list of vms sorted by any possible attributes, i.e. sorted by 
datacenter or cluster, not only by status.

  * For example, ovirt_vms_facts doesn't allow to get the datacenter the
    vm belongs to , and the pattern filter doesn't return a list of vms
    as expected:


- hosts: localhost
   connection: local
   tasks:
   - name: Get stopped VMs
     ovirt_vms_facts:
       auth:
         url: https://acore.v100.abes.fr/ovirt-engine/api
         username: admin at internal
         password: ovirt123
         insecure: true
         pattern: name=centos* and cluster=west
   - debug:
       var: ovirt_vms
   - shell: echo "{{ ovirt_vms.name }}"

How can I successfully display this list of vms like described here :
name 	description 	returned 	type 	sample
ovirt_vms 	List of dictionaries describing the VMs. VM attribues are 
mapped to dictionary keys, all VMs attributes can be found at following 
url: https://ovirt.example.com/ovirt-engine/api/model#types/vm. 	On 
success. 	list 	


  * About the python SDK:

list_vms.py could be what I expect, but vm.datacenter_name doesn't exist
