Add `GenerationEvent` as a possible event type to be emitted over a cluster stream. When a `GenerationEvent` is emitted, we should be able to get its topology as well as the start time of the new generation. Release note: None

…am client Previously, if the sinkless client loses connection, the processor would receive an error and move to draining. With the concept of generation, the sinkless client should send over a `GenerationEvent` once it has lost connection. On receiving a `GenerationEvent`, the processor should wait for a cutover signal to be sent (the mechanism for issuing cutover signals on new generation will be implemented in a following PR). Release note: None
