lets parse this html page with python, instead of snmp, to get the ink levels.

game plan

• use the chrome browser tools to inspect the html on the printer page, what element has the ink level?
• write a python script that talks to the printer at their ip address, how can we parse this element and get its ink level?
• follow this tutorial for prometheus https://www.youtube.com/watch?v=x3bSuGH8R28
• lets make a helper function below to fetch the html, and make it a part of the scrape_snmp function
• rename scrape_snmp to work
