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
Change-Id: I7a1ce4ba4ac358733747e9301038d0245ae08016
