  [WIP] add agent test scenario for agent automatic test #2905

---

New feature or improvement

• Describe the details and related test reports.

This PR works base on #2905 which @ascrutae does. The main purpose is to move the plugin-autotest back main repository.

1. There is a httpclient-scenario only here.
2. I don't add this to Jenkins's stages yet.
3. After this, I will add more scenarios for the tests.

We need the following steps first.

1. Make the license header clear. CI and e2e should pass.
2. Provide a detailed document about how to develop the plugin.
3. Provide document in development document about, how the plugin test works. give the potential contributor clear direction.
4. Support plugin test scenarios in JVM and Tomcat, with or without docker-compose, such as Kafka, MySQL.
5. Support parallel run tests in different VM(Jenkins), and have clear stage descriptions about which libraries tested in Jenkins UI.
