Subject: add stub for ssh keys

The idea is that in the future, the DataSources get_data could
check to see if there were ssh keys provided. if there were, it could
poll and wait (or inotify) until the <fp>.crt files appeared in the
/var/lib/walinux directory. Once they did, it'd populate the metadata's
public keys.
