Redirecting from HTTP to HTTPS creates issues with HttpClientFactory

Let's assume one has a TD with http entries but those links redirect to http**s**.
node-wot fails to properly handle those cases because the Http**s**ClientFactory is missing

Example TD at https://plugfest.thingweb.io/http-data-schema-thing
e.g., a link like http://plugfest.thingweb.io:80/http-data-schema-thing/properties/bool redirects to http**s**

Is it reasonable to combine those two client factories into one?
What was the rationale to keep them apart?
