IPA: warn if full_name_format is customized in server mode

https://fedorahosted.org/sssd/ticket/2009

If the IPA server mode is on and the SSSD is running on the IPA server,
then the server's extdom plugin calls getpwnam_r to read info about trusted
users from the AD server and return them to the clients that called the
extended operation.

The SSSD returns the subdomain users fully-qualified, ie "user@domain"
by default. The format of the fully qualified name is configurable.

However, the extdom plugin returns the user name without the domain
component.

With this patch, when ipa_server_mode is on, warn if the full_name_format
is set to a non-default value. That would prompt the admin to change the
format if he changed it to something exotic.
