Current Behavior

1. loaded collection
2. describe collection and collection. Loaded is always false
   

• case:

func TestLoadCollection(t *testing.T) {
	ctx := hp.CreateContext(t, time.Second*common.DefaultTimeout)
	mc := createDefaultMilvusClient(ctx, t)

	// create -> insert -> flush -> index -> load
	prepare, schema := hp.CollPrepare.CreateCollection(ctx, t, mc, hp.NewCreateCollectionParams(hp.Int64Vec), hp.TNewFieldsOption(), hp.TNewSchemaOption())
	prepare.InsertData(ctx, t, mc, hp.NewInsertParams(schema, common.DefaultNb), hp.TNewDataOption())
	//prepare.FlushData(ctx, t, mc, schema.CollectionName)
	prepare.CreateIndex(ctx, t, mc, hp.NewIndexParams(schema))

	// load two replicas
	loadTask, err := mc.LoadCollection(ctx, clientv2.NewLoadCollectionOption(schema.CollectionName))
	common.CheckErr(t, err, true)
	err = loadTask.Await(ctx)
	common.CheckErr(t, err, true)

	// describe collection
	coll, err := mc.DescribeCollection(ctx, clientv2.NewDescribeCollectionOption(schema.CollectionName))
	common.CheckErr(t, err, true)
	log.Debug("collection", zap.Bool("loaded", coll.Loaded))
	require.True(t, coll.Loaded)

	res, err := mc.Query(ctx, clientv2.NewQueryOption(schema.CollectionName).WithConsistencyLevel(entity.ClStrong).WithOutputFields([]string{common.QueryCountFieldName}))
	common.CheckErr(t, err, true)
	count, _ := res.GetColumn(common.QueryCountFieldName).GetAsInt64(0)
	require.EqualValues(t, common.DefaultNb, count)
}
