Add tests to ockam_transport_tcp

[jdspdx]

Ockam TCP transport provides Ockam Routing support over TCP connections.
The get-started guide has an introductory example of how the TCP transport can be used.

The happy path of TCP Transport works but we should add more unit as well as integration tests.

The functions in this crate are async, so an async testing strategy is needed.

@jared-s the introductory example link is broken

@louisgjohnson thank you for telling us 🙏
We were moving some examples around over the weekend. The correct link to a transport example is https://github.com/ockam-network/ockam/tree/develop/documentation/guides/rust/get-started/04-transport#readme

Glad to have found this issue! I realized the need for more tests while going through the in-depth documentation and I'd be happy to work on this under a mentor.

Hi @nk7608, do you still want to have a look at this issue and need some help to get started?
