[Node SDK] create POC for the SDK on Cloudflare workers

[ktrz-sre-is]

Adjust the SDK (either modify existing or create a new one) to allow using it on the Cloudflare Workers

Things to consider from initial investigation:

• Support for Node packages is limited. Can use node compatibility but it requires native Node modules to be imported with import syntax and with node: prefix which a lot of dependencies don't do.
• OpenTelemetry SDK context propagation uses parts of node:async_hooks that are not supported. Might need creating a custom one
• Background operations are tricky as Cloudflare Workers don't support async IO, timeouts are only available while handling a request (it can be either a fetch request handler or scheduled handler).
• Also worth noting that if something is scheduled in the handler it might actually never be executed unless ctx.waitUntil is used
