Initial otel implementation

[krissetto]

- What's this?
OTEL bits in the CLI

- Goal

The very first goal is to provide enough metrics to cover the compose wrapper's current usage (so we can then remove it).
To keep continuity with the current impl in the compose wrapper, these should include at minimum:

• command name;
• command duration;
• command status ("success"/"failure");
• command exit code

Pls note that the organization of the code is not final and will surely be adjusted as the implementation matures

- What I did

• Added some utils for otel related ops
• Implemented an initial version of otel metrics using the utils ^

- How I did it

Taking inspiration and adapting bits from buildx and the compose wrapper

- How to verify it

Manually. Automated tests still need to be defined

- Description for the changelog

- A picture of a cute animal (not mandatory but encouraged)

@jsternberg's PR #4889 just got merged 🥳

Can you rebase and see if everything's fine @krissetto?

[laurazard]

Just so I don't forget this, can you get code into telemetry.go to accept a OTEL_EXPORTER_OTLP_ENDPOINT env var in this PR too @krissetto?

[Benehiko]

From my side I think this is good. I'll approve so long to revert my "requested changes" :)

[laurazard]

LGTM 🥳 looks like there's a couple of linting errors, but other than that I'm happy with the current state of the PR.

[laurazard]

@jsternberg wanna take a final look? :')

A few more comments but this mostly looks good to me.
