Add smoke test for BEAM pipelines (#3037)

Created a smoke test to cover unit test gaps wrt BEAM:
- The Java and SDK compatibility in the pipeline container image
- The JPA setup in the pipelines

Both issues above can only be tested in a real pipeline.

This PR defines a new pipeline that performs a lightweight SQL
query and minimal processing. The build process can launch it
in a test environment to verify that the pipelines in the build
can run. The run script is also provided.
