Ideas

• Check that tasks exist (all those that are mentined in on-error, on-success on-complete etc.).

• Check all tasks are called.

• Check all tasks have an on-error/on-success or on-complete

• Check zaqar format

• Interactive workflow with zaqar posting the continue code.

• Check sub-workflows are provided the queue name
