proposal: chaos test

[idbeta]

1. Background
   In the real world, various faults may occur anytime and anywhere, such as sudden disk write failure, or sudden network disconnection in the computer room, etc. In order to more easily verify APISIX's tolerance for various faults, we need to perform chaos testing.
2. Purpose
   Check whether APISIX can work normally in the case of various external faults.
3. Method
   Thanks to @Yiyiyimu for recommending a good testing tool that can simulate various system failures--chaos-mesh, we can add a separate action to combine chaos-mesh to perform chaos testing on APISXI.
