docs: DEPRECATED: Change usages of this to {@link #onExecutionEmit} if you want to add a hook for each value emitted by the command
  or to {@link #onExecutionSuccess} if you want to add a hook when the command successfully executes
  
  Invoked after successful execution of {@link HystrixCommand#run()} with response value.
  In a {@link HystrixCommand} using {@link ExecutionIsolationStrategy#THREAD}, this will get invoked if the Hystrix thread
  successfully runs, regardless of whether the calling thread encountered a timeout.
  
  @param commandInstance
  The executing HystrixCommand instance.
  @param response
  from {@link HystrixCommand#run()}
  @return T response object that can be modified, decorated, replaced or just returned as a pass-thru.
