ceph-ansible fails with "you must set dashboard_admin_password and grafana_admin_password."

[Francesco Pantano]

During the overcloud deployment with ceph dashboard enabled, the playbook fails during the execution of "ceph-validate" role.
In particular, the task that double check that both grafana and dashboard admin password are set fails.
Passing the dashboard related template (-e /usr/share/openstack-tripleo-heat-templates/environment/ceph-dashboard.yaml) to the overcloud, we can see all the expected parameters in ceph-ansible workdir are set (included grafana and dashboard admin credentials).

    Move ceph-ansible required variables in the main group

    ceph-ansible v4.0.16 introduced some changes to double check
    the ceph dashboard and grafana passwords exist, are properly
    generated and are not defaults values.
    However, the constraint introduced forced tripleo to put
    these variables in all.yaml instead of distributing them on
    the related roles (mgr and grafana-server).
    This change moves these variables in ceph-base, since here
    we're able to generate the ceph_ansible_group_vars_all.

    Closes-Bug: #1867973
