/**
* This service does the required steps to add a directory as a deployment dependency and as an {@link ExternalModule}.
*
* Basically is used as an intermediate step in GlobalDirectoryDependencyProcessor to retrieve the global directories
* supplied by the services installed with the corresponding ee/global-directory resource. Those services are consumed here
* and for each supplied value an {@link ExternalModule} is created and added as system dependency to the current deployment.
