Add pipeline to test the docker image

[drebrez]

Would be nice to have a pipeline that test the docker image.

Possible flow:

1. checkout sources
2. build the docker image
3. startup mssql server
4. initialize the sakila database twice (see integration tests)
5. perform some changes in the second db
6. run the docker image
7. check the output (should have the differences performed at the step 5.)
