git-harry e148635e78 Add role system-crontab-coordination
Currently every host, both containers and bare metal, has a crontab
configured with the same values for minute, hour, day of week etc. This
means that there is the potential for a service interruption if, for
example, a cron job were to cause a service to restart.

This commit adds a new role which attempts to adjust the times defined
in the entries in the default /etc/crontab to reduce the overlap
between hosts.
