The e2e tests create a Secret for using with the RBD StorageClass. However this Secret was not used, instead the Rook generated Secret was linked in the StorageClass. By using our own Secret from the examples, Rook should not touch it when we make modifications. In addition, no modifications are needed for encryption anymore, as these are included in the example. Updates: #1795 Signed-off-by: Niels de Vos <ndevos@redhat.com>
