The node_internals _http_client.js emit a warn

[wang-ran]

Describe the bug
I use axios.get method with custom httpsAgent and httpAgent in node.js. The node_internals _http_client.js emit a warn when the server response http statue code 302 and headers location's protocol is different with the initiator url's protocol.

To Reproduce
Code snippet to reproduce, ideally that will work by pasting into something like https://npm.runkit.com/axios, a hosted solution, or a repository that illustrates the issue. If your problem is not reproducible, please file under Support or Usage Question

// Example code here
const axios = require("axios");
const https = require("https");
const http = require("http");
const httpsAgent = new https.Agent({keepAlive: true})
const httpAgent = new http.Agent({keepAlive: true})
const url = 'https://xxxxx';
axios
  .get(url, {
    httpsAgent,
    httpAgent
  })
  .then(() => {
    console.log("success");
  })
  .catch(() => {
    console.error("error:");
  });

I had read the axios' code , the httpFollow and httpsFollow's options should includes customer's agent

Expected behavior
axios use a new agent adapter the redirect url protocol

Environment:

• Axios Version: 0.19.0
• Node Version: v12.14.0
