> Currently HMS use the only proxy implementation of HMSHandler i.e {{RetryingHMSHandler}}, resulting in some code hacks in {{HMSHandler}}. For example when test HMS timeout, we add additional static fields {{testTimeoutEnabled}} and {{testTimeoutValue}}, and add sleep code in {{create_database}} method, which is not elegant and flexible.
> So we introduce a new conf {{metastore.hmshandler.proxy}} to configure proxy class for HMSHandler, it will be more convenient to extend the new proxy of HMSHandler and can separate test code from HMSHandler.
