Make user-default photosLocation configurable for administrators

[Input-BDF]

Is your feature request related to a problem? Please describe. In out Nextcloud setup we have al lot of shared group folders. To keep things more clear within users root directory and to "help" them to better find their own privat files and understand the difference between what is shared and what not, I plan to move most of the default application folders into the default_skeleton structure. For App like Notes or Talk administrators can define the default paths like "/Notes" or "/Talk"

Describe the solution you'd like I asume it would be helpful also for other administrators to have a occ command to define the default location occ config:app:set photos default_photos_folder --value="/Privat/Photos"

Describe alternatives you've considered The only alternative I found so far is to manipulate photosLocation in DEFAULT_CONFIGS UserConfigService.php but this is not a satisfying and update save solution. Am I missing something?

It would be even nicer, if this was implemented in the GUI (administrator apps configuration page).
