Install crontab and start testing cron jobs

[JWizerd]

Since we now have the ability to scrape indeed and send email notifications we should build a cron that will scrape the test scraper.html every 10 minutes or something to get that functionality tested and working.

CRONs are now running in the docker container and script execution is being logged both via the logger and a crontab log file called /var/www/html/cronErrors.txt. Right now for testing purposes, the frequency is set to every minute. I've also removed the mongo docker stuff since we don't need a network or a mongo container since we're using an external service. I've commented out the cron so it's not implicitly sending us test emails every two minutes while we're working on other stuff.

Which external service are we using for mongo dude? I thought we would be using the container it self
