Using influxdb-client-python against v1.8.10 how do I do the equivalent to `client.get_list_database()`?

まだ誰も着手していません。

### Specifications

* Client Version: 1.35.0
* InfluxDB Version: 1.8.10
* Platform: Linux

The subject sums up my whole question, really. Using influxdb-client-python v1.35.0 against InfluxDB v1.8.10 how do I do the equivalent to `client.get_list_database()` from the older influxdb-python v5.3.1?

The docs say `Use this client library with InfluxDB 2.x and InfluxDB 1.8+` so I hoped there was an equivalent.

I tried `BucketsApi.find_buckets()` but that seems to only use the v2 API and therefore throws an exception following the 404 status.

### Code sample to reproduce problem

```python
from influxdb_client import InfluxDBClient as InfluxDBClient2, BucketsApi

with InfluxDBClient2(url='http://localhost:8086', token=':', org='-') as client:
bucket_client = BucketsApi(client)
buckets = bucket_client.find_buckets()
for bucket in buckets:
print(bucket)
```

### Expected behavior

To get the databases listed.

### Actual behavior

```console
Traceback (most recent call last):
File "mdsh.py", line 5, in
buckets = bucket_client.find_buckets()
File "/usr/local/lib/python3.7/site-packages/influxdb_client/client/bucket_api.py", line 119, in find_buckets

```

### Additional info

_No response_

Start with the BucketsApi.find_buckets() call and the InfluxDB 1.8.10 behavior described in the reproduction. Determine whether the client exposes an equivalent database-listing entry point; done means the expected databases can be listed against InfluxDB 1.8.10 without the reported 404.
