Overview of federation/sharing improvements

[jospoortvliet]

Just an overview of federation-related feature requests ;-)

Trusted servers

• add trusted servers via OCC command
• configure sharing of system address book with trusted servers - related: Limit federation directory exchange to group or exclude group and user account deletion not considered.
• Limit federated sharing to trusted servers
• Federation: Sync user groups with federation:sync-addressbooks

Federation features

• Federated comments
• Federated avatars
• Password protect federated shares
• Ownership transfer through federation
• Federation does not allow blocking resharing
• adding note to federated share
• federated file sharing in Talk
• Sync files on changes across servers (right now editing a federated share does not trigger notify_push) Add a sync option to federated shares
• request access when a resource isn't found (for internal links)
• Allow re-activating expired public shares for a limited time

UI and user experience related improvements

• Federated share indicator on file list
• Display when a federated share was created through "Add to your Nextcloud
• show federation-id in sharing details if file/folder is shared from another user
• polishing: Federated share is listed in internal shares
• federation UI/wording improvements
• Federation app cleaning up
• Nextcloud federation alias domain - I think related to discovery through email address
• Use LDAP user name instead of UUID for federated cloud id - related to Customised federated cloud id to prevent something like john.doe@mydomain.ltd@nextcloud.mydomain.ltd
