Make shares visible to other users

[Chrusti]

Steps to reproduce

1. User A creates folder XY and shares it with Customer A
2. User B does not see whether folder XY is already shared with Customer A or not
3. If User A is deleted, Customer A won't be able to acces the shared folder XY because sharing is removed

Expected behaviour

Every folder has its own sharing history. A group of users can see all shares of a specific folder. If a user is deleted the shared folders of this user should be mapped to the admin user or so.
As I was told, there is no switch to get this behaviour. In my opinion is nextcloud is not very usable for data exchange with customers without this feature. Maybe there is a workaround that I don't know. All shares should at least be visible to the admin user.

Actual behaviour

Very similar request to #6480 -> let's continue there.
