We also discussed this within the team and agreed that it would be better to add this to existing Slider component. So you better will be to create a new feature branch and change this PR to target that branch instead of master, locally reset this commit changes except the spec file, then run yarn create-component to add RangeSlider to react-slider to create a boilerplate code for new component

UPD: I forgot that create-component is intended for preview packages only. You can resolve the lint errors by adding the necessary exports to the react-components suite package and updating the story imports to pull from react-components
