[1925] Proposal: Add template option for nuxt.config.js

It would be awesome if we can set app.html template src in the config like we do with global css:

module.exports = {
  template: 'app.html',
}

or

module.exports = {
  template: {src: 'template/app.pug', lang: 'pug'},
}

In this way we can share template between multi nuxt apps.
