Introducing Vercel Drains: Complete observability data, anywhere

What this post added

Renamed 'Log Drains' to 'Vercel Drains' to reflect expanded capabilities beyond logs. Added support for exporting OpenTelemetry traces, Web Analytics events, and Speed Insights metrics. Enhanced data correlation by enriching logs with trace and span IDs. Introduced two drain types: Custom drains (HTTP endpoints with configurable data types, sampling rates, formats like JSON, NDJSON, Protobuf, and security options) and Integration drains (turnkey integrations with partners like Dash0, Statsig, Datadog, and Logflare).
