Migrate WebF website to use Vue.js SSR

[mistyharsh]

Vue.js provides excellent server-side rendering library Nuxt.js. It can also emit static website. We will harness this idea to migrate WebF website to Nuxt.js. Existing Gulp based system is hard to maintain and scale.
Hence, this is the change we are going to make.
