Wait for cluster to be in a fully consistent and online state in
`cluster_config_consistent`. We expect the `start_server` to create the
desired primaries and replicas before the start of the tests. With the
current setup, the replicas may not complete the sync with primaries and
can be in loading state. In some cases, the role of replicas can still
be master with the delay of propagation of replicate command. The tests
can show flaky behavior in such cases. Add a check that verifies the
nodes health status 'online' for the cluster consistency. Leverage the
deterministic order of `CLUSTER SLOTS` to consider the cluster as
consistent along with the nodes health status.
