iotests: 124 - transactional failure test

Use a transaction to request an incremental backup across two drives.
Coerce one of the jobs to fail, and then re-run the transaction.

Verify that no bitmap data was lost due to the partial transaction
failure.

To support the 'err-cancel' QMP argument name it's necessary for
transaction_action() to convert underscores in Python argument names
to hyphens for QMP argument names.
