Add SSL detection to Vaguer

[JonRay15]

For Console / Governance App / Block Explorer to use a datanode it needs to have SSL encryption in place.

(Note its not clear to me whether wallet needs this too or not...)

Therefore it would be useful to include SSL detection in the Vaguer code if that is possible.

I'm not totally familiar with how we store the data Vaguer outputs, or therefore the best way to try to record this, I could think of a few:

1. Have lack of SSL be a fixed penalty of some amount
2. Have lack of SSL completely zero the score
3. Include the ability to annotate with SSL status and then work out if we can pull this into the grafana monitoring too
