https-proxy-agent known bugs

Versions of `https-proxy-agent` prior to 2.2.3 are vulnerable to Machine-In-The-Middle. The package fails to enforce TLS on the socket if the proxy server responds the to the request with a HTTP status different than 200. This allows an attacker with access to the proxy server to intercept unencrypted communications, which may include sensitive information such as credentials. ## Recommendation Upgrade to version 3.0.0 or 2.2.3.

Versions of `https-proxy-agent` before 2.2.0 are vulnerable to denial of service. This is due to unsanitized options (proxy.auth) being passed to `Buffer()`. ## Recommendation Update to version 2.2.0 or later.
