Currently when a node is in initial sync (STARTUP2), running a query on a collection (except collections in local database) returns error "NotMasterOrSecondary":

> db.docs.find()
Error: error: {
    "operationTime" : Timestamp(0, 0),
    "ok" : 0,
    "errmsg" : "node is not in primary or recovering state",
    "code" : 13436,
    "codeName" : "NotMasterOrSecondary",
    "$clusterTime" : {
        "clusterTime" : Timestamp(1550198882, 1),
        "signature" : {
            "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
            "keyId" : NumberLong(0)
        }
    }
}

However, when we run the dbStats or collStats commands (on the collection that is syncing), the commands will just hang there, waiting for locks. Since the node is in STARTUP2 state (not ready for reads), will we consider just returning an error "NotMasterOrSecondary" for dbStats/collStats/listDatabases/etc commands (same as the {find}} command)?
