Issue:
bitswap/session: context-aware lifecycle
I'm trying to trace a content retrieval request via `ipfs get ...` with the actual bitswap interactions.

This is tricky though because a bitswap client session creates a [new disparate context](https://github.com/ipfs/boxo/blob/0f1ebacc7662d946946e3315c49241f6fb188b7c/bitswap/client/internal/session/session.go#L164). Then I also found [this comment](https://github.com/ipfs/boxo/blob/0f1ebacc7662d946946e3315c49241f6fb188b7c/bitswap/client/internal/session/session.go#L209) for the `Close()` method which only cancels the session context:

```go
// Session lifecycle is independent of the context used to create requests -
// canceling a request context does not close the session. When context-based
// automation is desired, Client.NewSession(ctx) uses context.AfterFunc to
// automatically close sessions when the context is canceled.
func (s *Session) Close() {
	s.cancel()
}
```

@gammazero I saw that this comment is from you. Is the meaning descriptive or normative? Is it just describing how it's working or stating how it's supposed to work?

Looking at the session lifecycle (checking where new sessions are created and closed) I can see that they are always tied to the context that instantiated the session. This to me indicates that a separate context for the session isn't needed which would enable proper context propagation and improve the tracing. As a nice byproduct, the `retrievalState` wouldn't need to be passed manually through the stack.

New sessions are created here:

https://github.com/ipfs/boxo/blob/0f1ebacc7662d946946e3315c49241f6fb188b7c/bitswap/client/client.go#L442-L483

and here:

https://github.com/ipfs/boxo/blob/0f1ebacc7662d946946e3315c49241f6fb188b7c/bitswap/client/client.go#L702-L725

Both calls tie the new session to the incoming context.

The same argument then actually trickles down to the `sessionWantSender` as its lifecycle is tied to the sessions':

https://github.com/ipfs/boxo/blob/0f1ebacc7662d946946e3315c49241f6fb188b7c/bitswap/client/internal/session/sessionwantsender.go#L117-L142

Hints from issue comments:
@lidel: Triage notes:
- we will look into this a part of wider investigation into traces regressions / need of improvement
- revisit once boxo has mentioned fixes@gammazero: > Is the meaning descriptive or normative

Is is supposed to be descriptive, but we may have an issue here causing this to not work as expected (in which case the comment becomes normative). We are currently working on the issue which is affecting our ability to collect tracing results.@gammazero: Here is the necessary fix: https://github.com/ipfs/boxo/pull/1059
