problem_statement: cluster.state(index='name')['routing_table'] not found in client 7.5.1
Using the most recent release of the Elasticsearch Python client (7.5.1 at this time), the cluster state endpoint is not defaulting to show `_all` keys.

### 7.5.1

```
client.cluster.state(index=idx).keys()
dict_keys(['cluster_name', 'cluster_uuid'])
```

### 7.1.1:

```
client.cluster.state(index=idx).keys()
dict_keys(['cluster_name', 'cluster_uuid', 'version', 'state_uuid', 'master_node', 'blocks', 'nodes', 'metadata', 'routing_table', 'routing_nodes'])
```

This omission, if intended, would seem to be something to change in a major release version, rather than a minor release.

This was detected and reported [here](https://github.com/elastic/support-dev-help/issues/10455#issue-558049925). This compels me to pin Curator at client version `elasticsearch==7.1.0` for now.
