Support new reportUnusedDisableDirectives option

Issue Description

I would like to run ESLint in Atom with specific CLI flags. Unless I haven't checked it propertly, this is not possible with linter-eslint.

The problem arose for me with ESLint 5 which conflicts with the rule eslint-comments/no-unused-disabled. This rule is to be deprecated and replaced with the CLI flag --report-unused-disable-directives.

Another option would be to add a configuration property for --report-unused-disabled-directives.

We are using the Node.js API, not the CLI interface so it's impossible to do this exactly as requested unfortunately.

For your specific flag it looks like there is a new CLIEngine option available that controls this behavior: reportUnusedDisableDirectives

I'll go ahead and change the title to reflect that as the goal of this 😉.

Yes sorry, that makes sense. Thanks!
