Subject: [PATCH] Add initContainers as dependency check
Lately, we encountered hick-ups when the dspace container comes up but
the postgres container is still missing (although the containers will
restart until both start in the right order).
Here we add one `initContainers` that will poll the postgres db until
success.
Address #60
