The metricbeat module for CouchDB crash when targetting CouchDB 3.1

**Metricbeat version** : 7.8.1  
**CouchDB version** : 3.1.0 (6 nodes cluster)  
**OS** : RedHat 7.8

```
# /etc/metricbeat/modules.d/couchdb.yaml
- module: couchdb
  metricsets ["server"]
  period: 10s
  hosts: ["localhost:5984/_node/_local/_stats"]
  username: admin
  password: ******

```

Starting metricbeat `metricbeat -e` shows:

```auto

I'm having the exact same issue with CouchDb 3.1.0 and Metricbeat 7.9.1.
