Feature request

What problem does this feature solve?

easy integration of google adsense, recaptcha, etc.

What does the proposed API look like?

// global scripts
// currently only available on `head`
{
scripts: [
    {
      src: 'https://www.google.com/recaptcha/api.js?render=...',
      defer: true,
      async: true,
      pos: 'before'
    }
  ]
},
// per page scripts
nav: [
  {
    text: "Home",
    link: "/", 
    scripts: [
      {
        src: 'https://www.google.com/recaptcha/api.js?render=...',
        defer: true,
        async: true,
        pos: 'before'
      }
    ]
  },
]

How should this be implemented in your opinion?

Are you willing to work on this yourself?**

yes

Thanks for your interest in VuePress, but:

1. For global scripts, we can use enhanceApp.js and some script loading lib (e.g loadjs) to implement it at userland. you can even inject it at the dev or prod template when we support Config the dev and build html template. #733

2. For per page scripts, the API you recommended is such complicated, why coupling it with nav config? The simplest way should be monitoring $route changes, and then loading the scripts that you want.
