close filecoin-project/venus#5316

改动 (Proposed Changes)

主要目的:
增加venus-wallet STM annotation.
实际修改:

• 补充venus-wallet的部分测试用例
• 小重构
  • ServeRPC函数, 可以从外部传入signal channel, 可以通过外部发送停止信号.
  • 移除了自定义jwt.HMACSHA类型的别名:common.APIAlg. 因为这是一个没有意义的重定义, 还容易导致循环引用.
• venus-wallet添加STM的注解

💁‍♂️ :有部分重构是在编写测试用例的时候才发现需要重构的, 实在不太好单独拆分成不同的commit, 所以, 在commit上混到一起了.
