ConnTagInfo defines the relevant information needed by connection context tagger.
RemoteAddr is the remote address of the corresponding connection.
LocalAddr is the local address of the corresponding connection.
	LocalAddr net.Addr
}
RPCTagInfo defines the relevant information needed by RPC context tagger.
FullMethodName is the RPC method in the format of /package.service/method.
FailFast indicates if this RPC is failfast. This field is only valid on client side, it's always false on server side.
	FailFast bool
}
Handler defines the interface for the related stats handling (e.g., RPCs, connections).
TagRPC can attach some information to the given context. The context used for the rest lifetime of the RPC will be derived from the returned context.
HandleRPC processes the RPC stats.
	HandleRPC(context.Context, RPCStats)
TagConn can attach some information to the given context. The returned context will be used for stats handling. For conn stats handling, the context used in HandleConn for this connection will be derived from the context returned. For RPC stats handling, - On server side, the context used in HandleRPC for all RPCs on this connection will be derived from the context returned. - On client side, the context is not derived from the context returned.
HandleConn processes the Conn stats.
	HandleConn(context.Context, ConnStats)
