Poc add zombienet

[pepoviola]

Hi @wirednkod, I open this as draft to check how we can integrate the test you need in zombienet. At the moment I switch to use native provider in the ci since podman just hungs spawning the pods.
If you have test that needs the chain-spec file and the endpoints of the nodes, we can add those to the feature file and will run inside the test-runner.

Thanks!

For context, it's not the Polkadot nodes that we want to test. We want to test whether substrate-connect successfully synchronizes with the chain that the Polkadot nodes are running.

Thank you @pepoviola . I will create a simple test for implementing what @tomaka describes and use the code of PR for testing purposes if you are ok with that.

If you have test that needs the chain-spec file and the endpoints of the nodes, we can add those to the feature file and will run inside the test-runner.

For that test the chainspecs (which should contain the spawned bootnodes) will be needed - I will check the repo of zombienet to figure out how to do this.

Thanks for the feedback @tomaka / @wirednkod, I use polkadot and the base smoke test from zombienet just to check how to integrate zombienet in GH Actions. @wirednkod ping me to work in your test case 👍

Thanks!

We need a slight timeout for pausing the process until Chain is initialised.
If this timeout is removed then the following error shows:

2022-02-03 17:22:25        RPC-CORE: subscribeNewHeads(): Header:: Chain is not initialised
2022-02-03 17:22:25             DRR: Chain is not initialised

unhandledRejection

We can use the sleep x command in the feature file instead of having in this scripts.

A new PR is addressing this.
