Publish TLS related info to webrequest via varnish so it can be correlated to the rest of webrequest info:
There are about 5 values that we want to track that all concatenated are probably smaller than a 255 string. We can later refine these comma separated value of similar into a map that we can query similar to how we do for user agent. This data is currently in graphana but it will be much more useful if it lived along webrequest data.
