A VPN plugin provides one or several service-types, like org.
freedesktop.NetworkManager.libreswan Certain plugins provide more then one service type, via aliases ( org.freedesktop.NetworkManager.openswan). This function looks up a service-type (or an alias) based on a name.
Preferably, the name can be a full service-type/alias of an installed plugin. Otherwise, it can be the name of a VPN plugin (in which case, the primary, non-aliased service-type is returned). Otherwise, it can be one of several well known short-names (which is a hard-coded list of types in libnm). On success, this returns a full qualified service-type (or an alias). It doesn't say, that such an plugin is actually available, but it could be retrieved via list_find_by_service.
