Add an example script for backing up the config

This requires git and lockfile-progs, and only backs up (see
the comments why).

# This is an example ganeti script that should be run from cron on all
# nodes; it will archive the ganeti configuration into a separate
# directory tree via GIT, so that it is possible to restore the
# history of cluster configuration changes if needed
# The script requires the lockfile-progs package and the git software
# Note that since Ganeti 2.0, is the authoritative source
# of configuration; as such, we don't need to backup the ssconf files,
# and the other files (server.pem, rapi.pem, hmac.key, known_hosts,
# etc.) do no hold critical data (they can be regenerated at will, as
# long as they are synchronised).

# We use a simple lock method, since our script should be fast enough
# (no network, not talking to ganeti-masterd) that we don't expect to
# run over 5 minutes if the system is healthy
