Base Plugin Deprecated

I'll submit a PR if I can get this working. Right now, I've just copied handler.lua and shcema.lua into the relevant subdir and made the changes recommended above. I'm hoping that works

this is the handler.lua:

        local plugin = {
          VERSION  = "1.0.0",
          PRIORITY = 800,
        }

        local function escape_hyphen(conf)
            local path_prefix = conf.path_prefix
            local should_escape = conf.escape

            if should_escape then
                return string.gsub(path_prefix, "%-", "%%%1")
            end

            return path_prefix
        end

        local function add_header(conf, path)
            local forwarded_header = conf.forwarded_header
            if forwarded_header then
                kong.log("Adding Header: X-Forwarded-Prefix ", conf.path_prefix)
                ngx.var.upstream_x_forwarded_prefix = conf.path_prefix
            end
        end

        function plugin:access(plugin_conf)

            local service_path = ngx.ctx.service.path or ""
            local full_path = kong.request.get_path()
            local replace_match = escape_hyphen(plugin_conf)
            local path_without_prefix = full_path:gsub(replace_match, "", 1)

            if path_without_prefix == "" and service_path == "" then
                path_without_prefix = "/"
            end

            local new_path = path_without_prefix
            kong.log("rewriting ", full_path, " to ", path_without_prefix)
            if service_path ~= "" then
                kong.log("Prefixing request with service path ", service_path)
                new_path = service_path .. new_path
            end
            add_header(plugin_conf, path_without_prefix)
            kong.service.request.set_path(new_path)
        end

        return plugin
