test: add hydration parachain regression tests

[dmoka]

We added our first regressions tests using the provided framework.

@dmoka do you want to finish this?

Absolutely, thanks for the patience, I had some higher prior stuff to work on last week. Early next week I will look into this and wrap it up

@xlc For one of our tests ('moonbeam transfer DOT to hydration'), we would need to create a new block on the toChain.

But in the runXtokenstHorizontal method, new block is only crated in the fromChain.

As a solution, we could add a new param to runXtokenstHorizontal, with a function type, with name postAction (or so) that we could easily execute there.

What do you think? Or you might have a better solution in mind?

Chopsticks should automatically create new blocks on a chain when it receives an incoming XCM so you shouldn't need to manually create new block unless you need an additional block beyond the automatically created one.
What is the reason you need it? For example if it is the auto new block for XCM isn't working well, that's something we can fix in Chopsticks.

Hmm, now running it without using toChain.newBlock works well, the from and tochain balance checks are looking fine now. If you could double check it, that would be appreciated, otherwise LGTM from my point of view, thanks
