feat: display helia metrics in probelab

[SgtPooki]

Note: the probelab side of things is being documented at https://pl-strflt.notion.site/Helia-as-part-of-CMI-4ccbd109ce404f8fa4b4b02fd8af0b3f

Tasks

Preview Give feedback

1. Discover how Probelab is generating their metrics (talk with https://github.com/iand and https://github.com/dennis-tra)
2. Document gaps/blockers that exist in helia or https://github.com/plprobelab/caracol
3. Devise & finalize plan for getting Helia metrics into probelab
4. Execute the plan
5. Create js-libp2p docker image in plprobelab/parsec
6. figure out why js-libp2p agent_version isn't showing in probelab metrics (should be similar to js-libp2p/0.0.0 UserAgent=v16.15.1)
7. Document Helia configuration on probelab.io: docs: update TTFB graph explainer probe-lab/website#85

Notes from chat with @dennis-tra, @iand, and @achingbrain :

1. Already doing 3 experiments for DHT (parsec)
   1. Scheduler goes around to nodes 1x1, please provide CID, then waits, and asks other regions to request CID from DHT, and measures latency. (Kubo default config, Kubo with accelerated client, and Kubo with optimistic provide)
      1. We could add a 4th one, which is helia fleet. then we could test providing from helia, and requesting from kubo, and vice versa.
      2. Deployed via docker image (github://plprobelab/parsec)
         1. 4 methods we need to implement in helia docker image: https://github.com/plprobelab/parsec/blob/848e87a7dbb4652b999f855293cd8ac06e69b5f7/pkg/server/server.go#L180-L184
   2. retrieval success rate
   3. provide success rate
   4. time to first provider record

Note: This should be moved to the js-libp2p repo

I just finished documenting our parsec measurement tool. I have added a section Implementing a Server outlining the steps you'd need to take to be compatible with the rest of the infra. You need a libp2p host that supports the DHT protocol and these things:

1. Three HTTP endpoints that control the libp2p host. Documented here as an OpenAPI spec. For a rendering head over to https://editor-next.swagger.io/ -> File -> Import URL... -> paste: https://raw.githubusercontent.com/plprobelab/parsec/main/server.yaml
2. You need to write an entry to our postgres database with information about which configurations and dependencies the libp2p host uses (this is something I didn't anticipate in our call last Friday but is necessary, unfortunately)
3. Periodically update a row in our database (details in the repo's readme).

Hi @SgtPooki, I just wanted to check-in and see if this is still on the roadmap :) I'm asking just out of curiosity because I would love to see a performance comparison 👍

@SgtPooki quick follow up to see if this will be prioritised from your end so that we include it at probelab.io and allocate any resources to help out and get it to the finish line. Thanks!

This is in progress now and we should see some results in 2-3 hours hopefully.

@SgtPooki : what's the relationship between this issue and #275 ?
