Generated code has dependency to transport.rs from different repo

[smw-wagnerma]

The generated code from a wsdl file with:

<soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http" />

generates code like this:

pub async fn delete_authentification<T: transport::Transport>(
    transport: &T,
    request: &beatns::DeleteAuthentificationRequest
) -> Result<beatns::DeleteAuthentificationResponse, transport::Error> {
    transport::request(transport, request).await
}

with dependency to a transport module. To compile this code I have to include code from transport.rs from

https://github.com/lumeohq/onvif-rs/blob/main/schema/src/transport.rs

For better usability consider to generate a complete SOAP HTTP client for wsdl descriptions, like https://github.com/mibes404/zeep with dependencies to tokio and reqwest.

[WhyNotHugo]

Currently this Transport type is here:

https://github.com/lumeohq/onvif-rs/blob/main/transport/src/lib.rs#L31

I think this can possible be defined as a subtype of tower::Service, which should really facilitate using this directly with hyper.

In general, there are two approaches to this issue:

• Add a runtime dependency on a small crate which includes this Transport type and other helpers (and just import from there).
• Include the Transport type in the generated code output.

The former requires a bit more work on the consumer side, but also makes the whole experience smoother. The latter is simpler, but an annoyance to anybody using more than one SOAP service.
