This interface is needed when using the various script options in
lightdm (others?) configuration file. I'm using with 'display-setup-script'
and 'greeter-setup-script', but I suspect the same would be useful for
'display-stopped-script', 'session-cleanup-script' and others. In these
cases lightdm will be executing a configured script to perform some action
during the specified phase of the greeter/session. But without this interface
there is no way to transition into a new domain to execute the action.
