Bug#933032: Add Salsa-CI integration

[Otto Kekäläinen]

Package: mariadb-connector-java

Hello!

Could you please add Salsa-CI integration?
This add confidence that everything works and makes it easier to test
for regressions before upload.

MR available at

Additionally you also need to activate the CI from the project settings.
