Update to Apache HttpClient v5

[hakanai]

For external reasons we would like to update to Apache HttpClient v5.x, but currently Sardine has a hard dependency on v4.x, which forces us to keep around two implementations of all our HTTP code.

It would be nice if Sardine updated to v5.x also.

Sure. PR welcome.

I've figured out how to do most of it. Where I'm currently stuck:

• DefaultRedirectStrategy is very different to before. isRedirectable is gone, as is getRedirect
• HttpClientContext.TARGET_AUTH_STATE and AuthState itself are both gone
• RequestAcceptEncoding and ResponseContentEncoding are both gone

Partial work: https://github.com/hakanai/sardine/tree/apache-http5

I would like to take over this issue, as no update has been given in the last 2 years, would that be ok?

Any updates here? I think it would be great to have http/2 support, but its only achivable by having HttpClient 5
