feat(twitter): Add proxy support on twitter node.

[Bigous]

Currently almost all node-red supports proxy when you set the http_proxy environment variable.

Twitter node does not support it because it depends on oauth package and it does not support proxys (there are at least 5 pull requests to add proxy support to it, some of them from 2012 but none was accepted) so you cannot authenticate so you cannot work with it behind a proxy.

The message we receive points to clock, etc... It could be changed too (the error that came is ETIMEDOUT - it has nothing to do with clock)

My suggestion here is to depend only from request which already supports oauth.

Very frustrating!
