 Currently `options` have `intervalInMs` to control the polling interval, `resumeFrom` to enable resuming from a serialized state, and `lroResourceLocationConfig` which could determine where to find the results of the LRO after the operation is finished. Typically, Autorest figures out the value for `LroResourceLocationConfig` from the `x-ms-long-running-operation-options` swagger extension. If there are new arguments to be added to the class, they could be added to the options type.

 This class implements the `LongRunningOperation<T>` interface and is auto-generated by Autorest. `LroImpl` needs access to a few pieces: operation specification and operation arguments and a primitive function that can take them as input to send a request and converts the received response into one of type `LroResponse<T>` which has both the flattened and the raw responses.
