Pekko http request-timeout prevents spans from ending

[samwright]

Describe the bug

When pekko's HTTP server is configured with a request-timeout (default 20s) the span is never ended, and its response status code is never set.

Here's an attempt at fixing that, including a test that fails without the changes: #13435

I imagine the same solution would work with akka-http.

Steps to reproduce

See testTimeout

Expected behavior

The span should:

• end
• status set to error
• http.response.status_code set to the status code of the HttpResponse returned by Timeout-Access (defaults to 503)

Actual behavior

The span doesn't end, so doesn't get exported.
