cephadm: add a test case to cover generating init containers

Add a test case that covers the act of setting init_containers in
the deploy config on a custom container instance. This test executes
custom containers that both specify custom volume_mounts and not,
which are expected to "inherit" the volume_mounts of the primary
container's config.
