The key file deletion process is in the shell script commonly used by
all of encryption-open, encryption-open-metadata, and
encryption-open-wal init containers. The key file is deleted at the
encryption-open init container and encryption-open-metadata and
encryption-open-wal init containers are failed to open the key file.
The key file is in the /etc/ceph folder. Unless that folder is shared,
the key file anyway won't be available in the other init containers
even if it is not deleted by these init containers. And it will
naturally anyway be deleted after the init containers are
completed. So The key file deletion process in shell scripts is
unnecessary.
