api/vod: Implement last mile for Catalyst pipeline

[victorges]

What does this pull request do? Explain your changes. (required)

This implements the last missing pieces to get the E2E flow from Catalyst.

These felt merely bureaucratic so I didn't worry too much about getting it
implemented before we got an e2e flow with task-runner+catalyst first.
Ended up taking a couple of development hours tho so here I am, with the
testing session happening in less than a day lol

Specific updates (required)

• Create separate OS config for catalyst files
• Handle task output properly
• Create files field in asset to hold the output from task-runner
• Return proper playback and download URL for catalyst assets

-

• How did you test each of these updates (required)
  Upload some files through VOD pipeline.

Does this pull request close any open issues?
