vmware_drs_group_manager does not add or remove vm from vm group

[Pedmu]

SUMMARY

The module does not add an existing VM in an existing vm group
vmware_drs_group_info reports the VM as missing in the group

I have the same issue if I want to remove a vm from a group.
Meaning, it does nothing although the vm exists in the group
