Test recovery, releated jobs
Make some simple jobs that process input files from a SAM project, and generate output files, and declare suitable parentage metadata with version etc.
and a second stage job that takes those files, and generates more.
(put all outputs in dcache scratch and declare them there)
and verify we can make dependent jobs run using the output of the previous
Also make the first stage jobs fail to process some files, and configure them to
launch recovery jobs.
