HTTPClient timeout overrides timeout set in `HTTPClient.execute(_:timeout:logger:)`

If I create a HTTPClient as follows

let httpClient = HTTPClient(
    eventLoopGroup: MultiThreadedEventLoopGroup.singleton,
    configuration: .init(timeout: Timeout(read: .seconds(90))
)

and then call

let response = httpClient(request, timeout: .minutes(10), logger: logger)

the timeout in the execute call is ignored if it is longer than HTTPClient timeout.

This is particularly frustrating as HTTPClient.shared sets the timeout to be 90 seconds

Start by tracing the HTTPClient(request, timeout:logger:) call and how its per-call timeout is combined with the HTTPClient configuration timeout. Confirm the behavior with a request using a timeout longer than the configured 90 seconds; done means the execute-call timeout is honored rather than capped by the client configuration.
