[PATCH guest-common,manager,docs 0/5] backup jobs: add a start window

[Thomas Lamprecht <t.lamprecht@proxmox.com>]

A backup job can run into business hours, for example when it has to
wait for other jobs first or backing up its guests takes longer than
planned, and nothing stops it from starting further guest backups then.

The new 'start-window' job option sets how many minutes after the
scheduled start guest backups may still begin. Running guest backups
finish, and guests not started in time are reported as skipped. The
window also bounds waiting for the global lock and for backup slots.
It counts from the scheduled time, so a missed run repeated later only
gets what is left of it.

This applies on top of the series "parallel guest backups and backup
concurrency limits" [0].
