Could we put it to initLabelRuleManager? It seems we use pdHTTPCli only in initLabelRuleManager.

Later we will integrate the PD HTTP client into the Placement Rule manager below also, so I keep it initialized here.

+	labelRules := make([]*pd.LabelRule, 0, len(setRules))
+	for _, rule := range setRules {
+		labelRules = append(labelRules, (*pd.LabelRule)(rule))


Does changing the type of setRules(line157) to pd.LabelRule also eliminate the need for conversions?

The main consideration here is that TiDB has made additional extensions to the SQL layer concept for the Rule type internally. Therefore, I decided to keep the relevant implementation of the Rule type in TiDB and hide the type conversion in the lower layer from the caller. Otherwise, we would have needed to completely replace Rule with pd.LabelRule, or constantly introduce type conversions throughout. However, prioritizing code readability over a slight performance sacrifice seems like a better choice.
