Removed need for UpdaterService in MuonDetLayerMeasurements

The UpdaterService is not thread-safe and therefore must be removed. MuonDetLayerMeasurments was the only user of UpdaterService in production jobs. The use of the UpdaterService was replaced with the new cacheIdentifier() information from the edm::Event. The cacheIdentifier() can be used to quickly check to see if an edm::Event has changed since the last call to a method.
