Add telemetry, OTEL, logger...

[samber]

Debugging IoC is a pain.

An OTEL plugin listening to lifecycle events would be very nice.

Requires #73.

I imagine an API similar to this:

import (
    "github.com/samber/do/v2"
    "github.com/samber/do/observability/otel/v2"
)

injector := do.New()
otel.Listen(injector, ...) // <-- handling every available hooks

@samber This would add a bunch of dependencies though.
