Allow Ceph server some time to start

Browse Source 
Ceph server needs to create our "foo" volume on startup. It keeps the image
small, however it makes the server container start slow.

Add sleep before the server is usable. Without this PR, all pods that use Ceph
fail to start for couple of seconds with cryptic "image foo not found" error
and it clutters logs and pod logs and makes it harder to spot real errors.
