Cannot spin up ECS GPU worker with current versions

**Describe the issue**:
My GPU worker cannot start via the
```
"command": [
"dask-cuda-worker" if self._worker_gpu else "dask-worker",
"--nthreads",
"{}".format(
max(int(self._worker_cpu / 1024), 1)
if self._worker_nthreads is None
else self._worker_nthreads
),
"--memory-limit",
"{}MB".format(int(self._worker_mem)),
"--death-timeout",
"60",
]
```
that gets passed in from `ecs.py`. Dask-cuda seems to have removed the `--death-timeout` option, so upon startup of the worker, I see
```
Usage: dask-cuda-worker [OPTIONS] [SCHEDULER] [PRELOAD_ARGV]...
Try 'dask-cuda-worker --help' for help.

Error: Got unexpected extra argument: (60)
```
I'm unfortunately trying to run this from prefect, so I can't pin to a low enough version of dask-cuda and distributed that do have this argument specified. When I try to pin to a low enough version on the scheduler/worker container, the more recent distributed version on the prefect agent container doesn't seem to play nice with the scheduler/worker with the error (from the prefect agent):
```

**Minimal Complete Verifiable Example**:
run a docker image with the following, and you should see the error.
```
RUN pip install prefect distributed dask-cuda dask
CMD ["dask-cuda-worker", "--nthreads", "1", "--death-timeout", "60"]
```

**Anything else we need to know?**:
