[libgovirt] utils: Rename ovirt_rest_xml_node_get_content_va() to ovirt_rest_xml_node_find()

[Christophe Fergeau <teuf src gnome org>]

commit d606e30ac9e7b2e8b1cfcdc74a8dea877e82ae85

    utils: Rename ovirt_rest_xml_node_get_content_va() to ovirt_rest_xml_node_find()
    
    It is more useful to make this function retrieve a sub node and let the
    caller do what it wants with that node, instead of returning the content
    directly.
