feat: add consistency_check tool

[pro-spild]

使用方法为先执行写入操作，再执行读取操作，最后执行一致性检查操作。两次操作的k-v参数必须完全一致，随机种子也必须一致。 使用场景为检测主从同步一致性，以及重启/升级前后数据一致性。 检测原理为先写入数据，从主从节点分别读取数据，最后比较两次读取的数据是否一致。或者比较生成的写数据和读取的数据是否一致。

Walkthrough

This pull request introduces a new consistency check tool designed for Redis environments. New documentation, Go source files, and shell scripts have been added. The changes include detailed usage instructions, command mapping for read/write operations, helper functions for command generation, and the core logic for checking consistency across master and slave nodes. Additionally, a Go module file has been included to manage dependencies, and shell scripts facilitate concurrent execution of write and consistency-check operations.

Changes

File(s)	Change Summary
tools/.../README_CN.md	Added documentation detailing usage, compilation, supported parameters, operational modes, and example commands for the consistency check tool.
tools/.../{commands.go, common.go, consistency.go}	Introduced core tool logic including command mappings, helper functions for generating and transforming command strings, and a complete consistency check mechanism with flag parsing, client management, concurrent execution, and result comparison.
tools/.../{consistencyCheck.sh, write.sh}	Added shell scripts to execute the tool in different modes concurrently with specific parameters and logging for various operations.
tools/.../go.mod	Created a Go module file specifying the module name, Go version, and managing direct and indirect dependencies for the project.

Poem

Hoppity-hop, I bounce with cheer,
Codes and scripts now crystal clear.
Carrots of commands lined in a row,
Consistency blooms and starts to grow.
I nibble on changes, light and free,
A jazzy dance in our code garden—yee!

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
