Create PR build for TRSS

[llxia]

We should create PR build for TRSS to do the basic checks. GitHub workflow can be used for creating PR build.

Two possible ways for setting up the environment:

• install the prerequisites (nodejs, MongoDB) on GitHub runner directly
• or launch docker image in GitHub runner

In the first stage, we can just verify TRSS can start successfully. We can insert sample data and add more API tests at a later stage.
