Patero + Thumbnail

[jmrunge]

When using patero for ingest, caspa cant show thumbnails from videos. Perhaps this could be fixed in patero by allowing to specify different output dirs for each process (transcode/filmstrip/thumbnail). Today all is saved into output dir. Putting issue here because caspa is the one where the issue is seen.

Needs to go to the admin. Three paths must be the same as caspa. I think @pardo-bsso will be working on that
