much nicer split and organization of the patch series and each commit builds
and tests successfully, great!

How those schedules and datastore stuff is organized in the GUI is still open,
but that should not be a blocker for this series, can be done afterwards -
Dominik and I had already some discussion about this.
@Dominik, would be good if we could hatch a more specific plan for this tomorrow.

There are two things which I find a bit "weird" or not ideal with the verification
schedule settings.

1. Why a "Verify Job ID" (possibly also s/Verify/Verification/)?
   The user already has the comment fields for notes, and forcing them to give
   each job a name makes no sense, IMO. I know that an ID is required for working
   with each schedule, but that could be internal and automatically derived.
   Either by choosing some random UUID assigned on add, similar to what we do in
   PVE for backup jobs, or, alternatively join all relevant settings (datastore id,
   schedule, days valid, ignore verified) and use that as ID (e.g., encoded or
   md5sum'd) - this could even help to avoid that user specify the exact same job
   multiple times.
   However, the ID has to go IMO, this is not something a user will often specify
   when interfacing with the PBS, like the Datstore id is, but a schedule which one
   normally does not names. (naming is not only hard for Devs, it's also hard for
   users)

2. documentation is missing

3. there was something besides that, but it's late and I'm really have to stop
   working for today ^^

Anyway, it seems to work (from a few quick tests), I'd like to have a quick talk
with Dominik tomorrow (mostly about point 1. above) and then I'd apply this,
UX stuff can then be followed up.

thanks!
