Fixes a couple of lint errors caught by `npm run lint` in timeline- overview.js and timeline-viewport.js. Also restructures the test- details controller to use appropriate `this.` syntax instead of `$scope.` In addition, eslint and eslint-config-openstack have been updated, and a new .eslintrc.json config file has been created to tweak some specific rules for stackviz.
