Create subdomain for censorship wiki

It would be nice to have a shorter domain name for the censorship wiki. Currently it is hosted here:

https://trac.torproject.org/projects/tor/wiki/doc/OONI/censorshipwiki

Ideally I would like it to be possible to reach it via

censorshipwiki.torproject.org

I am not sure what is the best way to do this.

Valid options are:

1. Have it do a 302 to https://trac.torproject.org/projects/tor/wiki/doc/OONI/censorshipwiki

2. Run another instance of trac

3. Configure the current one to understand that for that certain domain name it should serve the content under that page (probably non trivial)

I would for the time being go for option 1) and discuss the other options before going for either or.
