Update transport implementations

[MarcoPolo]

No framework changes. Just updating the transports and attempting to have CI run on self hosted runners.

[MarcoPolo]

@dhuseby Are the self hosted runners expected to run?

[dhuseby]

I think the smart thing to do here is to set up Github runners.

[MarcoPolo]

I don't follow. Are you saying that the self hosted runners you previously setup for this repo are no longer available, and that I should use GitHub hosted runners instead?

[dhuseby]

I can set up one of the self-hosted runners for this repo to use. Let me do that, you'll need it. The GH hosted runners won't run long enough to do a full transport interop pass with this framework.

[dhuseby]

It's going to fail because it is running a custom Debian OS set up for the other testing framework. As you debug it, let me know what you need installed in the system image to make it work and I'll get them installed.

[dhuseby]

It is being picked up by the self-hosted runner but it is hanging I think.

[dhuseby]

Ok, the self-hosted runner is set up for your exclusive use. I manually ran the job several times to ensure that it is being picked up and run correctly. Everything is working. Let me know if you have any issues. The job is failing, but it is running correctly.

[MarcoPolo]

Interop tests ran fine: https://github.com/libp2p/test-plans/actions/runs/22320731122?pr=833

CI returns failure because some interop test cases failed. Worth debugging why those fail, but for the purpose of this PR, getting CI running again, we can ignore those.

[MarcoPolo]

This PR doesn't change anything about the test framework itself (except an explicit string casting in yaml), so I'll go ahead and merge this so future PRs can use CI properly.

I noticed you're manually installing dependencies. If you'd like me to upstream these into the self-hosted runner, let me know. I'm happy to apply a patch, rebuild and restart the runner. Here's the current Dockerfile for the ephemeral self-hosted runner:
