Motivation: Since commit 5021255 ("cells: simplify initialization of LocationManagerConnector") the connector is created without cell arguments. However, those arguments were forwarded to LocationMgrTunnel, which reads the `role` option passed from batch files. Thus, it always fall-backed to SATELLITE. As a result, a core domain that connects to another core domain announces itself as a satellite. The connecting core installs a default route to its peer, and the accepting core allows forwarding of messages received through that tunnel. Messages published to a topic are then delivered by every core domain along the default route chain, e.g. billing records show up two or three times in setups with multiple core domains. Modification: Pass the domain role explicitly to LocationManagerConnector and from there to LocationMgrTunnel through a dedicated constructor, instead of relying on forwarded cell arguments. Add unit test to cover the regression. Result: Core domains no longer install default routes to other core domains and messages sent to a topic are delivered only once. No more duplicate billing records in setups with multiple core domains.
