example playbooks: ipaselfservice examples mentioned ipadelegation.

The example playbooks for ipaselfservice were using the wrong module,
ipadelegation. This patch changes the references from ipadelegation
to ipaselfservice on these example playbooks.

Also, the attributes were changed, so the same attributes are used
throughout the examples.
