Cron: Support KS/UI forms

[mjansenDatabay]

With this commit cron job implementations
are allowed to migrate from legacy forms
to the UI/KS forms.

An instance of ilCronJob can provide a
boolean false when overriding usesLegacyForms
and then simply provide own implementations of
getCustomConfigurationSections and
saveCustomConfiguration.

Since this (kind of) adds new methods to the public interface (here: abstract base class) and contains an announcement regarding future removals of methods, I'll tag this PR with the JF label.

Hi @mjansenDatabay,

really looking forward to this!

I have two questions:

• For my curiosity about that new #[\Deprecated(...)] construction: Is the second parameter a version?
• Regarding the design: For the Activities we are currently trying to solve a somewhat similar problem. We decided to just use FormInput there. Due to the monoidal structure of the inputs, we can simply treat a group of (sections of groups of ...) inputs as a simple input. This makes the interface simpler but also the implementation on our end, while still offering a great deal of flexibility to our users. Did you consider this option too? Is there a strong reason to use an array of sections here?

Kind regards!

Hi @klees ,

For my curiosity about that new #[\Deprecated(...)] construction: Is the second parameter a version?

Yes, that's the ILIAS version. I used the syntax shown here https://wiki.php.net/rfc/deprecated_attribute .

Regarding the design

To answers this, I'll have to first study the references you mentioned above. I will, but not before January (tomorrow is my last working day in 2024).

Best regards,
Michael
