remove some debug logging

* cleanup code for URL type

* fix makefile for trace mode

* refactor, merge Entry, RawEntry and Route into one. 

* Implement fileserver.

* refactor: rename HTTPRoute to ReverseProxyRoute to avoid confusion

* refactor: move metrics logger to middleware package

- fix prometheus metrics for load balanced routes
  - route will now fail when health monitor fail to start

* fix extra output of ls-* commands by defer initializaing stuff, speed up start time

* add test for path traversal attack, small fix on FileServer.Start method

* rename rule.on.bypass to pass

* refactor and fixed map-to-map  deserialization

* updated route loading logic

* schemas: add "add_prefix" option to modify_request middleware


* updated route JSONMarshalling

-## Getting Started
+## Prerequisites
 
-### Setup
+Setup DNS Records point to machine which runs `GoDoxy`, e.g.
+
+- A Record: `*.y.z` -> `10.0.10.1`
+- AAAA Record: `*.y.z` -> `::ffff:a00:a01`
+
+## Setup
+
+1.  Pull the latest docker images
 
-1.  Pull docker image 
-    
     ```shell
     docker pull ghcr.io/yusing/go-proxy:latest
     ```
 
-2.  Create new directory, `cd` into it, then run setup, or [set up manually](#manual-setup) 
+2.  Create new directory, `cd` into it, then run setup, or [set up manually](#manual-setup)
 
     ```shell
-    docker run --rm -v .:/setup ghcr.io/yusing/go-proxy /app/go-proxy setup
-    # Then set the JWT secret
-    sed -i "s|GOPROXY_API_JWT_SECRET=.*|GOPROXY_API_JWT_SECRET=$(openssl rand -base64 32)|g" .env
+    docker run --rm -v .:/setup ghcr.io/yusing/go-proxy /app/godoxy setup
     ```
 
-3.  Setup DNS Records point to machine which runs `go-proxy`, e.g.
+3.  _(Optional)_ setup `docker-socket-proxy` other docker nodes (see [Multi docker nodes setup](https://github.com/yusing/go-proxy/wiki/Configurations#multi-docker-nodes-setup)) then add them inside `config.yml`
 
-    -   A Record: `*.y.z` -> `10.0.10.1`
-    -   AAAA Record: `*.y.z` -> `::ffff:a00:a01`
+4.  Start the container `docker compose up -d`
 
-4.  Setup `docker-socket-proxy` other docker nodes _(if any)_ (see [Multi docker nodes setup](https://github.com/yusing/go-proxy/wiki/Configurations#multi-docker-nodes-setup)) and then them inside `config.yml`
-
-5.  Run go-proxy `docker compose up -d` 
-    then list all routes to see if further configurations are needed:
-    `docker exec go-proxy /app/go-proxy ls-routes`
-
-6.  You may now do some extra configuration
-    -   With text editor (e.g. Visual Studio Code)
-    -   With Web UI via `http://localhost:3000` or `https://gp.y.z`
-    -   For more info, [See Wiki]([wiki](https://github.com/yusing/go-proxy/wiki))

-## 入門指南
+## 前置需求
 
-### 安裝
+設置 DNS 記錄指向運行 `GoDoxy` 的機器，例如：
 
-1. 抓取Docker鏡像
+- A 記錄：`*.y.z` -> `10.0.10.1`
+- AAAA 記錄：`*.y.z` -> `::ffff:a00:a01`
+
+## 安裝
+
+1.  拉取最新的 Docker 映像
 
     ```shell
     docker pull ghcr.io/yusing/go-proxy:latest
     ```
 
-2. 建立新的目錄，並切換到該目錄，並執行
-   
-   ```shell
-    docker run --rm -v .:/setup ghcr.io/yusing/go-proxy /app/go-proxy setup
+2.  建立新目錄，`cd` 進入後運行安裝，或[手動安裝](#手動安裝)
+
+    ```shell
+    docker run --rm -v .:/setup ghcr.io/yusing/go-proxy /app/godoxy setup
     ```
 
-3. 設置 DNS 記錄，例如：
+3.  _（可選）_ 設置其他 Docker 節點的 `docker-socket-proxy`（參見 [多 Docker 節點設置](https://github.com/yusing/go-proxy/wiki/Configurations#multi-docker-nodes-setup)），然後在 `config.yml` 中添加它們
 
-    - A 記錄: `*.y.z` -> `10.0.10.1`
-    - AAAA 記錄: `*.y.z` -> `::ffff:a00:a01`
+4.  啟動容器 `docker compose up -d`
 
-4. 配置 `docker-socket-proxy` 其他 Docker 節點（如有） (參見 [範例](docs/docker_socket_proxy.md)) 然後加到 `config.yml` 中
+5.  大功告成!可前往WebUI `https://gp.domain.com` 進行額外的配置
 
-5. 大功告成，你可以做一些額外的配置
-    - 使用文本編輯器 (推薦 Visual Studio Code [參見 VSCode 使用 schema](#vscode-中使用-json-schema))
-    - 或通過 `http://localhost:3000` 使用網頁配置編輯器
-    - 詳情請參閱 [docker.md](docs/docker.md)
