Support proxy headers for CONNECT requests

[omribahumi]

Curl has been supporting this for a while (says here), and it is also possible with requests by overriding the proxy_headers() method of HTTPAdapter.

How hard would it be to implement this in aiohttp?

[omribahumi]

Looks like this is the part of the code I need to modify:
https://github.com/KeepSafe/aiohttp/blob/add3bd9e32b0712dfaa4466194e165145a46e6d4/aiohttp/connector.py#L646

I can even implement this in my own connector.

seems you found solution

[dshoe1989]

Is there an official solution to this or is the suggested solution to just to create your own connector that extends TCPConnector and add support for it there?

[asvetlov]

As workaround you could extend TCPConnector right now.
But if you would make a Pull Request with adding proxy_headers parameter to session.request() API -- you are welcome.
Honestly I feel the request is rare so I have no motivation for implementing it myself.
