Route support unsecure HTTP but when HTTPS is used, A Grade cert is required
You can use HTTP for a route to post meaning it supports unsecured communication but when you switch to HTTPS, it enforces A Grade HTTPs certs.
We should be able to use self-issued or lower grade certs. Similar to curl -k, mailgun route should support "skip cert validation".
This is especially important for our QA, Stage type environments where buying highest grade cert financially does not make any sense
