CI/CD pipeline setup

[reboottime]

The Process

CI Process

For any pull request (maybe more strict on push request) on any branches, run following steps

• lint code
• build code
• test code
  • unit test
  • integration test
  • end 2 end test

CD Process

• For any push event on ['dev', 'sandbox', 'main'] branch
• Run CI
• Run deploy
