Do styling changes in openst-platform to follow the common style guide followed across all openst repos.

PROBLEM : Making sure a coding style is properly followed is a big undertaking, it often slips through the cracks leaving the work inconsistent across repos.

SOLUTION We came across Prettier https://prettier.io/ that automatically style the code. This will help the codebase be uniform and easier to read alongwith saving good amount of our time.

Prettier supports:

JavaScript, including ES2017 JSX Flow TypeScript CSS, Less, and SCSS JSON GraphQL Markdown, including GFM YAML It removes all original styling and ensures the outputted code conforms to a consistent style. (See this post)
