config_file: iterate over keys in the order they were added

Currently, all configuration entries were only held in a string map,
making iteration order mostly based on the hash of each entry's key. Now
that we have extended the `diskfile_entries` structure by a list of
config entries, we can effectively iterate through entries in the order
they were added, though.
