Add check-webcron.sh script to monitor webcron jobs
This commit adds a new bash script that monitors webcron jobs. The script takes in options such as proxy server, warning and critical levels, and URL to be monitored. It then checks the status of the URL and returns an exit code based on whether it is OK, Warning or Critical.
