On the current master branch, the expected output from valhalla_export_edges appears to be combined with logs. As far as I can tell, the standard logging facility must be going to stdout, which causes the output to be mixed. It seems the workaround for now is probably to create a new config specifically for exporting edges with mjolnir.logging configured to output to a file.

Long-term fix ideas:

• I would expect these to go to stderr, but I may be missing some reason why it's useful for these to go to stdout.
• Alternately, we could have valhalla_export_edges require a file argument to which the contents will be written. I don't know all the history, but the major use case for this command (Pelias) consumes a file on disk.

Thoughts?
