Run integration tests with encryption

[PVince81]

Run the same integration tests we already have but with encryption enabled.

It should be possible to enable it from the CLI in run.sh after passing an option.
This would at least guarantee that everything that works without encryption also works with encryption.

And as extension, the same could be done with the master key mode.

Might need adjusting Jenkins file, I'd suggest running the tests with encryption in a separate step/scenario so we can get separate results. Or simply make them run within the existing step that already runs integration tests.
