Minimize disk usage for daemon

[LeoWelter]

Analog to AsamK/signal-cli#1124

We send wildcam images, but there is no need to store them on the server (the actual captured images go to an S3 bucket)

Is there a way to use the ‘ignore attachments’ option for the default docker image auto receive settings?

Just realized this isn't documented anywhere, but you can set the AUTO_RECEIVE_SCHEDULE_IGNORE_ATTACHMENTS and the AUTO_RECEIVE_SCHEDULE_IGNORE_STORIES environment variables to true in the docker compose file to accomplish that.
