athena: setup upload priority

[nelsonjchen]

As a comma connect user, I would like my human-initiated "interactive" uploads prioritized over automated Firehose Mode uploads so it feels more responsive.

1. Have Firehose mode on (or I suspect just being on a branch of great interest to comma)
2. Automated Firehose mode segments are queued for upload.
3. Go to comma Connect, choose upload files or segments.
4. View Uploads for device, see the human chosen upload files or segments are queued behind automated firehose segments. This can be a 5-10 segment delay before the human chosen segments are finally uploaded.

Workaround: Cancel All Segments and requeue desired segments for upload.

Bounty is for setting up the priority-based upload in athena.

Must have a good unit test around it.

this can't be achieved w/o passing the "intent" or requester to athenad (intent = Intent.COMMA_CONNECT | Intent.FIREHOSE).

is this something that can be added on the connect / firehose service backends?

EDIT: i see supported params are defined by athenad. impl can be done before the private backends are updated
