Description
### Steps to Reproduce
servicecomb3.2.2版本问题，性能劣化，火焰图分析：
org.apache.servicecomb.router.custom.RouterServerListFilter#enabled，
org.apache.servicecomb.loadbalance.LoadBalanceFilter#getOrCreateLoadBalancer调用org.apache.servicecomb.loadbalance.Configuration#getRuleStrategyName，
org.apache.servicecomb.loadbalance.filter.ZoneAwareDiscoveryFilter#enabled，
org.apache.servicecomb.registry.discovery.InstanceStatusDiscoveryFilter#enabled，
org.apache.servicecomb.core.invocation.InvocationFactory#setSrcMicroservice调用readServiceName()，每次consumer调用都要重复去spring获取上面五个属性，导致consumer操作CPU消耗比2.X多近10倍
