http.proxy support by request module

[satokaz]

Thank you for making useful extension.

However, since the proxy environment is not considered, I can not always use it. So I made two changes.

• Use request module instead of hyperquest
• Use http.proxy setting of vscode's settings.json

hyperrequest does not support proxy. So I replaced it with request module.

Thank you for responding to the request! I confirmed that it works under a proxy environment.

Thanks. Kazuyuki
