Description

In #19129, atagar says:

For what it's worth stem's descriptor downloader *doesn't* use fallback directories because they lack extrainfo descriptors...

https://gitweb.torproject.org/stem.git/commit/?id=758f632

This is fine. Tor doesn't need it (nor does it need the DirPort). However, if you want the fallbacks to relieve DirAuth load from other sources such as stem then these are both issues.

We could easily add a 'extrainfo=1' to each fallback that supported extrainfo at the time we chose them. Then teach tor to parse or ignore it, because at the time tor is fetching extra-infos, it has already bootstrapped and has an up-to-date list.

I'm not going to get time to do these in 0.3.2.
Moving them to 0.3.3.
