[libgovirt] api: Implement ovirt_api_get_vms()

    api: Implement ovirt_api_get_vms()
    
    This returns an OvirtCollection that can then be used to fetch
    the actual list of VMs. Having the fetching code in a generic
    OvirtCollection class avoids to have multiple ovirt_api_fetch_xxx()
    methods for each collectionb, as well as the async variants.
