tests: do not fully override previous ceph_conf_overrides

We run an initial deployment with `osd_pool_default_size: 1` in
`ceph_conf_overrides`.
When re-running the playbook to test idempotency and handlers, we reset
`ceph_conf_overrides`, we must append a new value instead of just
overwritting it, otherwise, this can lead to error in the CI.
