Auth Request Authorization - HMAC signature verification Reference: https://github.com/nginx/njs-examples/blob/master/njs/http/authorization/auth_request.js

This handler verifies that the Signature header contains a valid HMAC-SHA1 of URI + query args. If valid, proxies to backend. Otherwise returns 401. Note: Uses js_content directly since auth_request module not available.
