Consider running the server on Cloudflare Workers

[robinplace]

Cloudflare's new serverless Workers platform may be a perfect platform for Melon's small server.

Highlights:

• Room codes: their API supports a simple key-value store that supports key listing, prefixes, and expiration:

• Payments: if we add accounts/payments at some point Cloudflare can run request-response work with a payment processor.
• Analytics: again, the KV store can keep logs and usage information no problem.

Still needs investigation:

• Cost: what's an estimated monthly cost once we pass the free tier?
• Migration: Vendor lock-in is a concern. What would it take to migrate data out to AWS Lambda or another serverless platform if needed?
