Improve delete all job performance

delete-all command was deleting one job at a time using the jenkins
doDelete rest endpoint which is very slow.  Change Ia4fbfca970165
allows us to execute a groovy script on the jenkins server to
do the same thing.  The only difference is that running the script
on the server will delete all jobs much faster.

As a data point:
I added all (~5,000) openstack jobs to my jenkins server.
The previous delete_all took many hours to delete all the
jobs while the script method did it in a matter of seconds.
