crunch-run handling non-group readable files in output directory
Some tools apply a 0200 mask to their output. This breaks crunch-run which relies on group rw permission to be able to upload and then clean up the output files. The crunch-run user cannot change the permission bits of files it does not own. Investigate and determine how to handle this situation.
1) Run uploader inside container (crunchrunner strategy)
2) Match container user to host user (cwltool strategy)
3) Exclusively use arv-mount for output (would require improved POSIX compatability)
4) Pass-through filesystem to remap permissions (haven't anything like this yet)
