[sheepdog] [PATCH 2/4] http: use REQUEST_URI instead of DOCUMENT_URI

[Liu Yuan]

Current code will segfault if we don't specify DOCUMENT_URI in nginx conf file.
And we should use REQUEST_URI because REQUEST_URI includes the Query String
(?q=testing...) where DOCUMENT_URI does not. ? is needed for container list
operation.
