dashboard: manage password backward compatibility

The ceph dashboard changed the way the password are provided via the
CLI.
This breaks the backward compatibility when using a recent ceph-ansible
version with ceph release without that feature.
This patch adds tasks for legacy workflow (ceph release without that
feature) in ceph-dashboard role.
