Arduino Add support for http proxy to esp8266 http client

Fixes https://github.com/esp8266/Arduino/issues/8085

I was able to verify this works with my proxy setup, it would be good for others to test as well, I'm no expert on how proxies are configured.

I do very little c++ so don't be afraid to give me lots of feedback :)

@ChrisSmith Do you think you can solve the conflict, or do you need help ? I/someone will merge right after the fix

Hey @d-a-v I don't have time to resolve the conflict and test at the moment. You should be able to resolve + commit to this branch if you'd like. Otherwise I'll get to it when I am free

https://github.com/esp8266/Arduino/pull/8237 also broke this even more, so I don't mind fixing this instead of @d-a-v
