logs: provide a syslog drain

[cldellow]

We've been using Apex Logs for a few months and really like the minimalist, "just works" approach you've built!

We currently use it for structured logs, but if it was easy, we'd love to dump our unstructured logs in to a separate Apex Logs project for ease of searching. We host on render.com, and it looks like they support dumping console logs to a syslog drain

This may not be a great fit for Apex since it'd be unstructured data, but would you consider adding a syslog drain to the current receiver?
