[Self-Hosted] Allow endpoint to use "http" protocol

[jorioux]

📋 Description

I'm running shields.io self-hosted on kubernetes.

I have a second service that returns JSON to generate custom badges in this format:

{
  "schemaVersion": 1,
  "label": "hello",
  "message": "sweet world",
  "color": "orange"
}

Right now, my badges URL looks like this:

https://shields.domain.com/endpoint?url=https://custombadges.domain.com/service1/health

Since shields and my custom badges service are running on Kubernetes, Shields should be able to call an endpoint on the same namespace (using Kubernetes internal DNS) in http like this:

https://shields.domain.com/endpoint?url=http://custombadges/service1/health

Proposition

Could you add the option to not force the https protocol when calling an endpoint?
