Add verbosity when using '-force' command line option.

[ruralroots]

I wanted additional verbosity both from the daily cron run and when manually running the ./gen_wg_config.sh using '-f' command line option. I have added this code snippet to gen_wg_config.sh after line 122 that addresses the issue.

        echo "TODAYS DATE"              # Display Run Date
        echo ""${now}""                 # and Time
        echo ""                         #
        echo "KEYS EXPIRE ON:"          # Display Authentication Token
        echo "${expire_date}"           # Expiry Date and Time
        logger -t SSWG "RUN DATE:${now}   KEYS EXPIRE ON: ${expire_date}"       # Log Status Information
