* WIP: http_proxy implemented, first steps for https_proxy #1440

* add HTTP_PROXY support to upgrade_command and WIP: tunneling

* WIP async handshake, stuck on WANT_READ, try to defer  + check

* create and upgrade with proxy working, TLS and non-TLS to proxy TLS working

* bun install/upgrade/create working with http(s)_proxy #1440

* add NO_PROXY support #1440

* remove commented code and add TODO
