find_old_style_container_sync_settings.py

"""
Script to find any old-style full urls x-container-sync-to settings.

Run as the user that Swift runs as and give the script one or more
container directories to scan, such as:

python find_old_style_container_sync_settings.py /srv/node/*/containers

It will output a line per find: account/container x-container-sync-to-value

Such as:

AUTH_test/test2 http://127.0.0.1/v1/a/c

Since there could be multiple replicas of the same container, you
probably want to collect all the output and then run it through: sort -u
