Review Comment:
instead of passing all of these in can the constructor take in a
`Function<WindmillConnection, WindmillStreamSender>
windmillStreamPoolSenderFactory`
or create a WindmillStreamPoolSenderFactory.java interface
```
@FunctionalInterface
interface WindmillStreamPoolSenderFactory {
WindmillStreamSender create(WindmillConnection connection);
}
```
then in `StreamingDataflowWorker.java` you can pass in
```
connection -> WindmillStreamPoolSender.create(
connection,
GetWorkRequest.newBuilder()
.setClientId(jobHeader.getClientId())
.setJobId(jobHeader.getJobId())
.setProjectId(jobHeader.getProjectId())
.setWorkerId(jobHeader.getWorkerId())
.setMaxItems(totalGetWorkBudget.items())
.setMaxBytes(totalGetWorkBudget.bytes())
.build(),
GetWorkBudget.noBudget(),
streamFactory,
streamPoolWorkCommitter,
streamPoolGetDataClient,
streamPoolHeartbeatSender,
streamingWorkScheduler,
waitForResources,
computationStateFetcher)
```
and in `createAndStartWindmillStreamSender`
you can call `windmillStreamPoolSenderFactory.create()` /
`windmillStreamPoolSenderFactory.apply(connection)`
since it seems like all of those params are just added to create the
WindmillStreamPoolSender
