forever-agent does not work with Node 0.12

Moving #1421 (comment) since this technically doesn't block request from working unless the forever option is enabled

I'm using the forever option with request. Starting 0.12 this option leads to ENOTSOCK and ECONNRESET errors. This never works presumably because the HTTP Agent API changed quite a bit with node 0.12. eg:

var request = require('./index').forever({maxSockets: 1});
request('http://www.yahoo.com', function (error, response, body) {
    if (error) {
        console.log(error);
    } else {
        console.log(response.statusCode);
    }
});

leads to

{ [Error: connect ENOTSOCK] code: 'ENOTSOCK', errno: 'ENOTSOCK', syscall: 'connect' }

vs on node 0.10 it logs

It seems like it would help to write a regression test for this.
