switch from jshint/jscs to eslint

no issue
- drop `jshint`, `jscs`, and `ember-suave` dependencies
- remove `grunt` related linting dependencies and tasks
- remove linting build from Travis so that linting can be performed as part of the normal test suite (refs TryGhost/Ghost#7427)
- add `ember-cli-eslint` and `eslint-plugin-ember-suave` dependencies
- configure `eslint` to match our previous coding style
- update config to run eslint tests as part of the normal test run
- add `npm run lint` command to only run linter tests
