This argument is in the central list for hysterical raisins (mostly me
being a doofus) but is used in almost none of them. Document it
explicitly in each module to stop the confusion.

Without this patch, the os_keystone_domain module is not idempotent if
the description is empty because the description parameter is None in
ansible, but the keystone client returns an empty unicode string.
Following the example of other OpenStack modules, this patch fixes the
issue by checking whether the module parameter is None before going on
to check its value.
