Runtime Filter: Reduce useless logs

[elsa0520]

Enhancement

Some logs info shows the message which meaning can be directly displayed by default behavior. So we don't need to addition log it.

For example, the runtime filter could not support the hash join which is running in TiDB. This is the default behavior of Runtime Filter. So when the planner meet the TiDB hash join, we don't need to log it by "RF only support TiFlash compute engine while storage type of hash join node is not TiFlash"

func (generator *RuntimeFilterGenerator) generateRuntimeFilterInterval(hashJoinPlan *PhysicalHashJoin) {
	// precondition: the storage type of hash join must be TiFlash
	if hashJoinPlan.storeTp != kv.TiFlash {
		logutil.BgLogger().Warn("RF only support TiFlash compute engine while storage type of hash join node is not TiFlash",
			zap.Int("PhysicalHashJoinId", hashJoinPlan.ID()),
			zap.String("StoreTP", hashJoinPlan.storeTp.Name()))
		return
	}
