add on failure parameter to imperative workflow

[berriperri]

Motivation: Why do you think this is important?

this functionality is in the base class and I don't see why not to expose it to imperative workflows

Goal: What should the final outcome look like, ideally?

class ImperativeWorkflow(WorkflowBase):
  def __init__(
          self,
          name: str,
          failure_policy: Optional[WorkflowFailurePolicy] = None,
          interruptible: bool = False,
          on_failure: Optional[Union[WorkflowBase, Task]] = None,
      ):
