HTTP mode - Pass QueryString along to upstream_url

[alexellis]

Expected Behaviour

QueryString should be available in the function when using HTTP mode

Current Behaviour

The QueryString is not forwarded or consumed by templates

Possible Solution

• Pass along to upstream_url.
• Update templates to read/pass the value
