Describe the bug

I want to get a response as string even if that comes as application/json. Parsing the response to an object is not required and not desired as the only thing I have to do with it is rewrite some urls and I am not sure of the content type the server will use.

To Reproduce

Server:

const http = require("http");
const server = http.createServer((req, res) => {
    res.writeHead(200, {"Content-Type": "application/json"});
    res.end("{\"doNotParse\": 1}");
});
server.listen(1234);

Client:

const axios = require("axios");   
axios.request({url: "http://localhost:1234/", responseType: "text"})
     .then(res => console.log("Type of data is %s", typeof res.data));

Outcome:

Type of data is object

Expected behavior
response data should be the string "{\"doNotParse\": 1}", the program would print:

Type of data is string

Environment:

• Axios 0.19.2
• Fedora 31
• Node 12

Additional context/Screenshots
Setting transformResponse: (data) => data appears to do the trick, regardless of responseType.
