    Improve parsing of cron schedule

    Improving the parsing of the cron schedule for /etc/cron/rabbitmq-stats.
    The code makes assumptions that the user in the cron entry will be the
    root user, which is generally safe as that's what the charm applied.
    However, the parsing is brittle in that it depends on the 'root' string
    in the entry. This changes the code so that the cron timer spec is
    stripped out based on the column entries in the file.
