dispatch: add fail-* family of hooks
The post-* family of hooks will not run in case a command fails (i.e.
raises an exception). This makes it inconvenient to hook into events
such as doing something in case of a failed push.
We catch all exceptions to run the failure hook. I am not sure if this
is too aggressive, but tests apparently pass.
