      In ReplicaSetAwareServiceRegistry::onInitialDataAvailable(), print out the name of each service signaled. 

      logd("onInitialDataAvailable for service {}", service->getServiceName());

      Run a simple 2 node replica set, the logs appear for the secondary, but not the primary.

      const rst = new ReplSetTest({nodes: 2});
rst.startSet();
rst.initiate();
const primary = rst.getPrimary();
assert.commandWorked(primary.getDB("test").myColl.insert({a: 1}));
rst.awaitReplication();
jsTest.log("Completed replicated insert but no log lines onInitialDataAvailable on the primary");

rst.stopSet();

      Starting up a new replica set, the "onInitialDataAvailable()" is never signaled on the primary of a fresh replica set with no previous data. This is confusing for users of the ReplicaSetAwareService API who rely on "onInitialDataAvailable()" to determine when data is consistent.
