feat(tests): add logic for integration tests

[clemsos]

Description

This PR updates the way we deploy Unlock's infrastructure to make sure we can run integration tests through it

NB: the new eth-node was split into #9648 so should review and merge that one first, then rebase it

~~NB: This needs to be rebased once #9462 is merged~~

The PR is passing without integration tests so far, so just the docker images and scripts to run everything. I will add the actual tests to another PR as this one is already big enough...

@clemsos Do you think all tests need to run hardhat? I wonder if this isn't going to make our life harder for e2e front-end tests?

the frontend e2e does not need to run hardhat but the subgraph does. We can have different testing logic in this repo with two different yarn tasks

also I think we should merge this PR once all the tests are green and work about more details in another one if possible
