have a url for saying the timestamp of the bridge data files
gman (operator of Serge) has been asking us to make sure that Serge is properly scp'ing the bridge descriptors and bridge network status files to bridgedb, after various hardware moves.
We thought of setting up some other .ssh "authorized command" approach so he can log in to the bridgedb server and ls that directory. But then I realized a better option would be: let's have bridgedb offer a url for saying when its input files were from.
Then we could use that url for easy prometheus / nagios freshness checking too.
Maybe we want to build this into rdsys because rdsys is the future, or maybe we want the feature in both bridgedb and rdsys. (I'm not sure how the rdsys roadmap timing looks.)
