Init JH QA environment

What does this MR do and why?

Related to #1036, setup a JH QA environment, like the jh/spec did.

Changes

1. Need include JH Env in qa/qa/specs/spec_helper.rb of upstream, like the unit test did in spec/spec_helper.rb.
2. Add jh/qa directory to serve a JH QA environment, then we can add our jh-only QA specs in it.
3. Refactor the Skip test, change the dir into jh/lib, then it can be reuse by JH QA.
