feat(swarm-test): allow publishing to crates.io

Allows folks like @bajtos to use the crate, see https://github.com/filecoin-station/zinnia/pull/85.

I opted for not exposing the crate through the `libp2p` meta crate as it is a testing tool only. @thomas
let me know if you prefer me to do so.

Pull-Request: #3629.
