Arvados

I started writing out some code snippits for operating on container requests based on the scripts at https://github.com/bcosc/arvados-tools

Ideas to add: (These are things I think I know how to do, but think other people would want) This all comes from a debugging standpoint and trying to get info out of a workflow as fast as possible.

Given a top level container request:

List output pdh of all child container requests
List output pdh of only some child container requests (maybe this is just a grep of listing all)

List inputs of all child container requests (not just the input yml, the pdhs and files)
List inputs of only some child container requests (maybe this is just a grep of listing all)

List all child failed container request uuids given top level uuid

List log file pdh given container request uuid

The parent uuids are inconsistent, and should just be one example: qr1hi-xvhdp-zzzzzzzzzzzzzzz

Please change all parent_request_uuid/container_request_uuids to qr1hi-xvhdp-zzzzzzzzzzzzzzz

Also maybe make this one also use qr1hi? So its consistent? maybe its nitpicking, so no big deal if this doesn't get changed.

collection_uuid="your-4zz18-collectionuuid"

Otherwise everything else lgtm, feel free to resolve when you make the changes.
