Designate DNS – tsigkeys, default sort key for ordering is “created_at” instead of the “ID”

[Arkady Shtempler]

According the Doc: https://docs.openstack.org/ ID is a default key:

Sorts the response by the this attribute value. Default is id. You can specify multiple pairs of sort key and sort direction query parameters. If you omit the sort direction in a pair, the API uses the natural sorting direction of the server attribute that is provided as the sort_key.

Actually the default key used in code is “created_at”
