Enhancement: Peristance / ttl no limit for redis streams

[darekmeco]

Summary

Could you add the ability to set an unlimited TTL (time-to-live) to the RedisChannelsStreamBackend, so that it’s possible to retrieve the history for the entire duration of the stream’s existence?

Basic Example

            plugins=[
                ChannelsPlugin(
                    arbitrary_channels_allowed=True,
                    backend=RedisChannelsStreamBackend(redis=client, stream_ttl=-1),
                )
            ],

Could you explain your use case for this?

If you don't set any TTL on the stream, you'll have to clean it up manually at some point, otherwise your redis will run out of memory eventually, which is why a default TTL has been added here.
