feat: Manage Trusted Servers via OCC command

[T0mWz]

Issue

As an administrator, I currently have to manually add each URL one by one as a trusted server via the Web Interface. From an administrative standpoint, the ability to add a single URL or a list of URLs via the shell would be highly desirable.

See submitted issue; #63439

Wish

Add an OCC option to list and manage federated trusted servers. This would eliminate the need for multiple clicks and copy-and-paste actions. But it also makes automated management easier.

Usage

occ federation:trusted-servers --list
occ federation:trusted-servers --add https://a.example.com https://b.example.com
occ federation:trusted-servers --remove https://a.example.com

Notes

• --list ignores the servers argument; --add/--remove require at least one URL — enforced via INVALID (exit 2) return codes.
• --remove takes a URL rather than an id (matching your ask), so findServerId() re-applies the same https:// prefix + trailing-slash trim that TrustedServers::addServer() used when the row was stored, then matches against getServers() to find the id removeServer(int $id) needs.
• Status codes (STATUS_OK etc.) are mapped to readable labels in the --list table.

It would be great if this was using the new AsCommand attribute, see for example the files app how this is done

I would prefer 3 sub commands federation:trusted-servers:add, federation:trusted-servers:remove and federation:trusted-servers:list.

You can have multiple command in a single class, see https://docs.nextcloud.com/server/latest/developer_manual/app_development/commands.html#multiple-commands-in-one-class
