cinder storage-init can't make admin keyring

[Jaesang Lee]

When install cinder with pre-installed ceph environment, there is error about make admin keyring in storage-init job.

In cinder, storage-init script was copied recently, but _ceph-admin-keyring.sh isn't. Like glance and gnocchi, cinder also should be contain _ceph-admin-keyring in chart.
