Remove OTEL stuff from "compose wrapper"

[krissetto]

Description

Goal:

Moving the OTEL bits and bobs out of the "compose wrapper", consolidating the features into the CLI itself, so we can later axe 🪓 the whole wrapper once all it's functionality has been moved/replaced.

Stuff to do:

• Create basic OTEL infra the CLI project
  (cli: add otel sdk tracing and metric providers to the core cli #4889 creates some basic sdk abstractions to share);
• Move basic OTEL helpers from the wrapper to the CLI project and adapt/create what's necessary.
  Check here for some of the current impl
• Move necessary logic from reporter.go and client.go in the wrapper to the CLI (adapting what's necessary to otel)
  Check reporter.go and client.go
• Use the new common OTEL bits to instrument the CLI project itself, recreating CLI specific metrics/traces initially defined in the wrapper (check if carrying Add OTEL support (carry 4556) #4698 is worth it). Done via Initial otel implementation #4940
• Adapt projs/plugins (eg compose, buildx, ...) to use the new shared code wherever possible
• Remove otel bits from the wrapper (optional if we already merged Introduce support for CLI plugin hooks #4376, since we can remove the whole wrapper)
• Profit
