Move jobs to db

[damienbfs]

In the next few prs:

• use job collection for archives (avoid duplicates, archive is now a model)
• remove permission verifications from db code, remove safety checks decorators (does_user_exist) -> move this to caller. -> will reduce number of calls to db and reduce lock contention.
