Remove SSL severity score histograms

* The SSL severity scores ended up not yielding promising results, so this CL
  removes them.
* This does not remove the histograms that track which errors were caused
  by specific causes.
* The "recently expired" heuristic is now being recorded as part of
  SSLInterstitialCause instead of as part of a severity score.
* The type of network connection is now being recorded as its own histogram
  instead of as part of a severity score.
