Ceph secrets are not used when specified by encrypted data bags

There are several cases where Ceph commands require a secret as input. For example, when populating the monitor daemon with the monitor map and keyring in the mon recipe, it requires the FSID secret:

`command lazy { "ceph-mon --mkfs -i #{node['hostname']} --fsid #{node['ceph']['fsid-secret']} --keyring #{keyring}" }`

This is fine until you decide to not store secrets as override attributes. If you put secrets in encrypted data bags, these node attributes are not populated and the deployment fails.
