Looks very solid. Just a few nitpicks

Doesn't it make sense to add Clone + Send + Sync trait bounds to this associated type since it looks like you impose them later in drink_client anyway?

requiring bounds on the associated type here would be a bit implementation-based, so I'm not convinced if it is the correct move
but anyway, even if I put these bounds here, I would have to keep them in the impl<AccountId, *> *Backend for *, so nothing to 'gain' here

Should we consider having a feature flag for this, since it is bringing in a few heavy substrate dependencies and (at the moment) is not the default backend.

fair point, I'll hide it tomorrow

~70 new dependencies, some of which are substrate crates (for state-machines, externalities, few pallets etc)

Finally we provide implementation of
E2EBackendtrait for a drink-based client. Also, we add a new argument fore2e-testmacro, enabling user to specify target backend architecture.Since
drinklibrary is pretty immature yet, we are lacking some functionalities like dry-running or events. Relevant places in code are marked with the corresponding issues in drink repository. We'll fix them in the near future.Notes:
