Is there an existing issue for this?

Current Behavior

1. specify an existing db name in ClientConfig and expected an error

   _, err := base.NewMilvusClient(ctx, &clientv2.ClientConfig{Address: *addr, DBName: "dbName"})
   common.CheckErr(t, err, false, "database not found")

2. specify an valid db name in ClientConfig, then create a collection in this db. However the collection in the default db

   func TestClientWithDb(t *testing.T) {
   teardownSuite := teardownTest(t)
   defer teardownSuite(t)
   ctx := hp.CreateContext(t, time.Second*common.DefaultTimeout)
   
   // connect with not existed db
   /*_, err := base.NewMilvusClient(ctx, &clientv2.ClientConfig{Address: *addr, DBName: "dbName"})
   common.CheckErr(t, err, false, "database not found")*/
   
   // connect default db -> create a collection in default db
   mcDefault, errDefault := base.NewMilvusClient(ctx, &clientv2.ClientConfig{
       Address: *addr,
       //DBName:  common.DefaultDb,
   })
   common.CheckErr(t, errDefault, true)
   _, defCol1 := hp.CollPrepare.CreateCollection(ctx, t, mcDefault, hp.NewCreateCollectionParams(hp.Int64Vec), hp.TNewFieldsOption(), hp.TNewSchemaOption())
   defCollections, _ := mcDefault.ListCollections(ctx, clientv2.NewListCollectionOption())
   require.Contains(t, defCollections, defCol1.CollectionName)
   log.Debug("default db collections:", zap.Any("default collections", defCollections))
   
   // create a db and create collection in db
   dbName := common.GenRandomString("db", 5)
   err := mcDefault.CreateDatabase(ctx, clientv2.NewCreateDatabaseOption(dbName))
   common.CheckErr(t, err, true)
   
   // and connect with db
   mcDb, err := base.NewMilvusClient(ctx, &clientv2.ClientConfig{
       Address: *addr,
       DBName:  dbName,
   })
   common.CheckErr(t, err, true)
   _, dbCol1 := hp.CollPrepare.CreateCollection(ctx, t, mcDb, hp.NewCreateCollectionParams(hp.Int64Vec), hp.TNewFieldsOption(), hp.TNewSchemaOption())
   
   dbCollections, _ := mcDb.ListCollections(ctx, clientv2.NewListCollectionOption())
   log.Debug("db collections:", zap.Any("db collections", dbCollections))
   require.Containsf(t, dbCollections, dbCol1.CollectionName, fmt.Sprintf("The collection %s not in: %v", dbCol1.CollectionName, dbCollections))
   
   // using default db and collection not in
   _ = mcDb.UsingDatabase(ctx, clientv2.NewUsingDatabaseOption(common.DefaultDb))
   defCollections, _ = mcDb.ListCollections(ctx, clientv2.NewListCollectionOption())
   require.NotContains(t, defCollections, dbCol1.CollectionName)
   
   // connect empty db (actually default db)
   mcEmpty, err := base.NewMilvusClient(ctx, &clientv2.ClientConfig{
       Address: *addr,
       DBName:  "",
   })
   common.CheckErr(t, err, true)
   defCollections, _ = mcEmpty.ListCollections(ctx, clientv2.NewListCollectionOption())
   require.Contains(t, defCollections, defCol1.CollectionName)
   }
