Add a way to execute a script upon job deletion

[wwadge]

This would be super useful to cleanup anything that has been created externally to jenkins eg pull down a VM.

All that would be required is a parameter for a script that gets executed together with a job name as a parameter.

I like this idea, but in a simpler form. What if we simply placed the names of all deleted jobs into an environment variable (sort of like how you can currently get WORKSPACE, JOB_NAME, JOB_URL, etc). Then that way you could simply add an Execute Shell build step after the build step that invokes the gradle script and use said environment variable to do whatever need be done.

Nice :-)

Looks like someone already forked and added the script delete support too though it's hard-coded at the moment:
