Pull request for gocql ssh/tls feature

Piggybacking on wiki tests and verified integration.sh test work locally. 


Dropping the limit is not acceptable unless discussed among the maintainers as this limit is in place to maintain coverage. This isn't just a mere setting that can be altered between PRs as per the users liking. 

Quite frankly 64% coverage in my opinion is low and we are shooting for 90+% so unless you have valid reasons that more than one maintainer agrees upon to drop the limit your provided tests must maintain or exceed the limit.
