Follow redirect

[Eomm]

Prerequisites

• I have written a descriptive issue title
• I have searched existing issues to ensure the feature has not already been requested

🚀 Feature Proposal

When a response has 301/302 status code, the inject should follow the redirects

Motivation

Ref fastify/help#664

Example

const response = await app.inject({
      url: '/asd',
      method: 'GET',
      followRedirect: true // default max 1 redirect
      // OR
      followRedirect: 10 // follow max 10 redirect
    });

I think this could be a plugin.
