[X] I'm submitting editing a platform

• [X] I looked at the original platform and followed a very similar methodology.
• [X] I maintained the docstring at the top of the existing platform file that is formatted exactly like rest.py
• [ ] I added sample code to any template app that this platform works for, look at deluge.ini in /template_apps/ for an example
• [X] I have thoroughly tested this platform and it works
• [ ] I am committed to updating this platform if something breaks it in the future

Info on changes

I needed to ignore the SSL errors generated when doing an HTTP check on some of my self hosted apps i run locally that have self-signed certs. I did NOT wish to lose the SSL verification check on ALL services I had on my dashboard, so I went ahead and made some changes to the http_status platform.

I did NOT check the example code box, because I could not reliably figure out how / where to edit the "data sources" section text or any other text really for that matter (im bad with templating in pytthon).

I did NOT check the maintenance box because, well, i cant. Trust me, you don't want me messing with the code long term. I am hoping these 4 or 5 lines are helpful, but it took me many hours to get just these few lines working.

You're not the only one... I only just today realized my previous pull requests included other commits unintentionally... so I asked the same thing.
