Add explicit certainty for Assert Nothings

tsellers-r7 commented 3 years ago

Description

This PR explicitly sets the certainty levels for certain Assert Nothing style fingerprint matches. The intent is to convey that all other matches to a banner or endpoint should be given priority over these specific matches. For example, a http_server match may be too generic to have value but the x509 issuer may also match and we want that second one to win always.

How Has This Been Tested?
