build: upgrade stack and bump to lodash4 (#193)

BREAKING CHANGE: replace Gruntfile.js by the common `@ovh-ux/component-rollup-config` configuration
  The `dist` folder architecture changed.

  Before:

  ```sh
  $ tree -L 1 dist/
  dist/
  ├── ovh-api-services.js
  └── ovh-api-services.min.js
  ```

  After:

  ```sh
  $ tree -L 2 dist/
  dist/
  ├── cjs
  │   ├── index.js
  │   └── index.js.map
  └── esm
      └── index.js
  ```
