**Apache Airflow version**:
2.0.2

**Kubernetes version (if you are using kubernetes)** (use `kubectl version`):
v1.18.18

**Environment**:
Cloud provider or hardware configuration: AWS


**What happened**:

Updated to Airflow 2.0.2 and a new warning appeared in webserver logs:
```
WARNING - Exception when importing 'airflow.providers.google.common.hooks.leveldb.LevelDBHook' from 'apache-airflow-providers-google' package: No module named 'airflow.providers.google.common.hooks.leveldb'
```

**What you expected to happen**:
No warning.

**How to reproduce it**:
Don't know the specific details. Have tried adding `pip install --upgrade apache-airflow-providers-google` but the error was still there.

**Anything else we need to know**:
I am not using LevelDB for anything in my code, as a result I don't understand from where this error is coming.
