Issue 1987047: Forwarding all http request headers when fetching a resource via ProxyHandler

[Gagandeep singh <ga...@gmail.com>]

Reviewers: *dev@shindig.apache.org*,

Description:

Currently ProxyHandler just takes in the proxyUri to fetch and totally ignores
the http request headers like "User-Agent".

This change passes on the HttpRequest object which has all the headers present
in original request - Host and Content-Length header.
