The CI report replica will return the error when performing CLUSTER
FAILOVER:
```
-ERR Master is down or failed, please use CLUSTER FAILOVER FORCE
```
This may because the primary state is fail or the cluster connection
is disconnected during the primary pause. In this PR, we added some
waits in wait_for_role, if the role is replica, we will wait for the
replication link and the cluster link to be ok.
