   InstanceAddressURL is shared for many threads which can reduce object allocation for each service. So, InstanceAddressURL  with different thread (or RpcServiceContext) can get difference parameters. You can think that InstanceAddressURL is aggregated with a lot of services in the same app, and we can get each service's parameter with current thread's state(RpcServiceContext).
