ianbuss opened a new issue, #23823:
URL: https://github.com/apache/airflow/issues/23823
### Apache Airflow version
2.3.0 (latest released)
### What happened
The `providers_manager.py` logs an import warning with stack trace (see
example) for optional provider features instead of an info message noting the
optional feature is disabled. Sample message:
```
[2022-05-19 21:46:53,065] {providers_manager.py:223} WARNING - Exception
when importing
'airflow.providers.google.cloud.hooks.compute_ssh.ComputeEngineSSHHook' from
'apache-airflow-providers-google' package
Traceback (most recent call last):

```
### What you think should happen instead
There is explicit code for catching `ModuleNotFoundException`s so these
import errors should be logged as info messages like:
```
[2022-05-20 08:18:54,680] {providers_manager.py:215} INFO - Optional
provider feature disabled when importing
'airflow.providers.google.cloud.hooks.compute_ssh.ComputeEngineSSHHook' from
'apache-airflow-providers-google' package
```
### How to reproduce
Install the `google` provider but do not install the `ssh` submodule (or
alternatively the `mysql` module). Various airflow components will produce the
above warning logs.
