Commit Message

xds: reimplement stats management (#7848)

This change reimplements stats recording for the client side:

1. Implemented the new stats objects: ClusterDropStats and ClusterLocalityStats, which match C-core's implementation. The XdsClient APIs for accessing stats objects are

- addClusterDropStats(String clusterName, String edsServiceName)
- addClusterLocalityStats(String clusterName, String edsServiceName, Locality locality)

2. Eliminated the LRS LB policy and incorporate locality load recording in ClusterImplLoadBalancer. The endpoint addresses resolved in ClusterResolverLoadBalancer will attach the locality in each address attributes. In ClusterImplLoadBalancer, its helper's createSubchannel() will populate the address locality and then call XdsClient.addClusterLocalityStats(...) to obtain the per-locality stats object for recording RPCs. This stats object is attached to the created subchannel's attribute. Therefore, ClusterImplLoadBalancer receives Picker update from its child LB policy, the Picker's subchannel will always have the per-locality stats object attached. Helper.pickSubchannel(...) will populate the per-locality stats object and wrap it into the stream tracer for counting RPCs. Note the subchannel's shutdown() is wrapped to call the stats object's Release().
