AsyncRedisSaver cannot be constructed outside an async context

[DanCardin]

The call to asyncio.get_running_loop() forces AsyncRedisSaver to be constructed in the context of a running event loop, despite not actually doing anything async in the constructor.

I have found myself forced to do the following in order to bypass this, since i cannot easily perform this construction in async-land at the moment.

def setup():
    checkpointer = asyncio.run(_redis_saver(client))
    ...
    uvicorn.run(...)


async def _redis_saver(client: Redis):
    return AsyncRedisSaver(redis_client=client)


async def lifespan():
    checkpointer.loop = asyncio.get_event_loop()
    await checkpointer.asetup()

@bsbodden I think you addressed this already!
