Known Issues / Planned Changes

• (common/fuzz) Rewrite querypartRule & headersPartRule tests with new methods/logic
• (core/inputs/formats) Replace http.ReadRequest with manual/custom parser as it is strict http request parser and does not support unsafe raw requests
• (core/inputs/formats) use OrderedParam to maintain Order of Headers while parsing (currently we use map[string][]string)
• (core/inputs/formats) fix failing input format test of openapi, json and raw request
• move package (pkg/protocols/common/fuzz) -> (pkg/fuzz) [ to avoid deep nested directories and easier access to fuzz module)
