add(751): add github actions to execute tests

- created workflow directory and test.yml workflow
- added a job that executes existing compose.test.yml file
  to run tests
- job will be triggered when a PR is raised to master or
  push happens to master ( post merge also will trigger a
  job )
- added concurrency check so that old job can be cancelled
  if a new push happens
