Allow args/kwargs for on_failure hook

[thomasLeMeur]

Today, we can add on_failure hook at message level. But this hook will only receive failed messages info (actor name, actor args, etc.).

For complex on_failure process, it will be nice to allow user to add args/kwargs to on_failure message (to give context data for example).

Ok, my bad. kwargs is given to on_failure actor.
