Add Resource Detectors to frontend service

[svrnm]

Changes

This will add resource detectors to the frontend service, to create richer data for the backend, e.g.:

Similar could be done for other languages/services, I just wanted to get started with Node.JS where I know how to do it :-)

Merge Requirements

For new features contributions please make sure you have completed the following
essential items:

• CHANGELOG.md updated to document new feature additions
• Appropriate documentation updates in the docs folder

@svrnm this is really cool!
Thanks for this PR.

We have something similar in Rust, but not with that many resourceDetectors.

@svrnm this is really cool! Thanks for this PR.

Happy to help & that you like it:-)
I will try to add some more eventually across the demo services :-)

We have something similar in Rust, but not with that many resourceDetectors.

There are implementations of container resource detection & cloud resource detection across many languages, so they can be used as a template for rust, since the mechanics are always the same (e.g. for container.id you need to read it from the right files, and for the cloud ones there are APIs).

@puckpuck / @julianocosta89 I feel like we should document the resource enrichment somewhere? Maybe a dedicated file to keep things simple or add to the attributes file

Thanks for the addition @svrnm! This looks great 🚀

@cartersocha is something to discuss in the SIG meeting in the new year, but I think we can put Resource detection in the feature/metric matrix tables. We should also document how it is accomplished in each service doc, similar to how we show other instrumentation features.
