Add log level to StreamHandler

[mbentz-uf]

What does this change do?

Set the log level of the StreamHandler.

Why was this change made?

The logs to the console did not contain DEBUG log entries. Updating the log level of the StreamHandler fixes this.

Verification

Run the sample script in PyCustodian with the latest changes to test.

1. In PyCustodian checkout PR 109
2. In pyproject.toml replace tag = "2.3.1" with rev = "9fd646c272336af7d436ddcc9fcad7c284e255d6"
   • https://github.com/ctsit/PyCustodian/blob/f45aa0617f6f0511501f5ecf4203c6a53dfb366f/pyproject.toml#L16
3. Run poetry upgrade
4. Run the sample script with and without the verbose flag
   • py-custodian run sample_script.py
   • py-custodian run sample_script.py --verbose

Verify that the logs contain DEBUG entries when the script is run using the --verbose flag, and are not included when run without the --verbose flag.
