test(inspec): add tests based on existing Serverspec tests (#168)

* ci(kitchen): use `openssh.config` as `state_top`
* Semi-automated using https://github.com/myii/ssf-formula/pull/33
* test(pillar): remove deprecated option and disabled method
* https://travis-ci.org/myii/openssh-formula/jobs/585340845#L1811-L1813:
* test(pillar): use same SSH options as used by Travis
* Using existing options locks out after `kitchen converge` (before `verify`)
* https://travis-ci.org/myii/openssh-formula/jobs/585356835#L2957-L2965:
* test(inspec): add tests based on existing Serverspec tests
* Follows on from #166
