New Feature for GN4.x: Public permalink to private md

Regarding PR 9059:
Hello @josegar74 . Thank you for attention. 9059 is a work in progress.
We are opening this topic to keep a record of this new feature outside of the PR. Your inputs are more than welcome especially regarding recommendations concerning the design.

We are not yet cleaning the code (adding headers, refactoring …)

Proposal is to allow an anonymous user to browse a private md given a permalink (actually a hash given as request parameter). It involves probably security concerns. Cheers !

Hi @sebr72,

For simplicity, please keep discussions inside the PR. That will make life of those reviewing the PR a lot lighter.

Thank you!
