[Bro-Dev] #928: Incorporate ICSI certificate notary into SSL logging

[Matthias Vallentin]

>  * type:  Test Case Missing => Merge Request

Unless we install a some dummy certificate for testing purposes in the
notary, we have no reliable way test that the notary returns the same
result twice. That's why I'm changing this ticket to Merge Request.
Moreover, the new functionality is not enabled by default, one has to
load the notary script in order to get the extra columns in the
ssl.log.
