We are trying to run cloudflared access tcp ... behind a squid proxy. However, the dialer doesn't support proxy. Meaning, we can't set https_proxy env. For example:

env https_proxy=http://myproxy:12345 ./cloudflared access tcp ...

Fails as the https_proxy isn't respected.
