Based on #5155

Adds a new revert_outbound_transfer extrinsic. Functionally, the new extrinsic is almost the same as finalize_inbound_transfer:

  1. It verifies that the caller is the operator
  2. It checks mint allowance
  3. It mints new tokens

The only difference is in input arguments and the emitted event.

Todo:

  • Add proper benchmarks and weights

LGTM!
@kdembler do you want me to handle the benchmark tests for this or are you gonna do that as well?

@freakstatic if you could do that, that'd be great

Logic looks ok, I have just left a few points

I assume that this is an identifier whose validity is already confirmed by the squid.
Given that there are no checks on this...

Namely the extr. assumes that transfer_id will refer to a pending transfer outbound request queued in the argo-squid

Correct, likewise we don't check it any way when calling finaliza_inbound_transfer. It all assumes that the operator is acting correctly

let caller = ensure_signed(origin)?;
ensure!(caller == Self::operator_account().unwrap(), Error::<T>::NotOperatorAccount);

ensure!(Self::status() == BridgeStatus::Active, Error::<T>::BridgeNotActive);

Should this be present?
I am thinking about the following scenario:

  1. Transaction outbound exists
  2. Bridge is paused
  3. User tries to revert transaction

Yes, when the bridge is paused, nothing should be callable. Also it's not user that reverts the transaction, it's the operator

});
}

Despite my previous comment I will point this out :
transfer revert failing test case for bridge status not active is missing

Yes, we should add this as well. Let me do this in next PR though, at this branch there are small issues with bridge status that I fixed on my next branch
