Vulnerabilities fixed

*Sourced from [The Node Security Working Group](https://github.com/nodejs/security-wg/blob/master/vuln/npm/505.json).* > **Man-in-the-Middle** > [https-proxy-agent] Socket returned without TLS upgrade on non-200 CONNECT response, allowing request data to be sent over unencrypted connection > > Affected versions: <2.2.3 *Sourced from [The npm Advisory Database](https://cwe.mitre.org/data/definitions/300.html).* > **Man-in-the-Middle (MitM)** > Affected versions of this package are vulnerable to Man-in-the-Middle (MitM). When targeting a HTTP proxy, https-proxy-agent opens a socket to the proxy, and sends the proxy server a CONNECT request. If the proxy server responds with something other than a HTTP response 200, https-proxy-agent incorrectly returns the socket without any TLS upgrade. This request data may contain basic auth credentials or other secrets, is sent over an unencrypted connection. A suitably positioned attacker could steal these secrets and impersonate the client. > > Affected versions: < 2.2.3
