update: Add support for post tools, add round limits, per-round token…

… configuration and per-round request time configuration #1206

Ⅰ. Describe what this PR did

fix #1206
增加了post method
增加了轮次限制，单论token限制以及单论请求时间限制
redis的支持，我没有加，因为考虑到有轮次的限制，不会出现内存装不下历史会话的情况，且由于每次请求完成后，历史记录就没用了，需要清掉，因此存储到持久化存储中没意义。

Ⅱ. Does this pull request fix one issue?

Ⅲ. Why don't you add test cases (unit test/integration test)?

Ⅳ. Describe how to verify it

Ⅴ. Special notes for reviews
