Ignore missing proxy when removing grid-type batch jobs. #3072

In the HTCondor-CE, we can have a grid job's sandbox disappear before
the gridmanager picks up the job for removal. The gridmanager
immeidately puts the job on hold because it can't read the proxy. But we
don't need the proxy to remove the job.

Delay Condor-C output file transfer until JobFinishedHookDone is set. #3379

When the schedd does file transfers, it accesses the job sandbox as the
condor user. Thus, the transfer of output files can fail if the sandbox
is still owned by the user. To guarantee that the job files are owned by
the condor user, the gridmanager must wait until JobFinishedHookDone is
set in the job ad.
