Requiring default props specified as ES6

[saihaj]

Is your feature request related to a problem? Please describe.
React is deprecating defaultProps on functional components and suggests to use ES6 default values (facebook/react#16210).

In order to stay future proof we will be disabling eslint rule for default props and continue with default values. But eslint can't throw error if we haven't specified a default value (where needed) and that depends when eslint-plugin-react resolves jsx-eslint/eslint-plugin-react#2396

Describe the solution you'd like
Update eslint config once that feature is released.
