[pve-devel] [RFC v2 qemu 1/3] Revert "PVE-Backup: modify job api"

[Stefan Reiter <s.reiter@proxmox.com>]

This reverts commit 640d758d467962e7e67b4aea867037f1304424af.

Signed-off-by: Stefan Reiter <s.reiter@proxmox.com>
---

Added in v2. Not necessary anymore with the transaction patches, the jobs are
automatically created in "JOB_STATUS_CREATED" and not running, so the sequential
transactions work without this as well. Removes even more custom patch code :)

On applying to pve-qemu you can of course just remove the patch instead of
applying the revert.
