fix: remote root handlers when they exist (#3128)
### Summary
In some environments, such as Google Colab, loggers have a root handling
that did not mask sensitive values. As a result, secrets such as API
keys appeared in the logs. The PR removes root handlers when they exist
to ensure sensitive values are handler properly.
### Testing
Run the following in a Colab notebook. You should see two log outputs,
one with the API key masked and one with it exposed.
```
!pip install unstructured
```
```python
import logging
import json
from unstructured.ingest.interfaces import (
ChunkingConfig,
EmbeddingConfig,
PartitionConfig,
ProcessorConfig,
ReadConfig,
)
partition_config = PartitionConfig(
partition_by_api=True,
api_key="super secret",
)
from unstructured.ingest.logger import ingest_log_streaming_init
ingest_log_streaming_init(logging.INFO)
logger = logging.getLogger("unstructured.ingest")
logger.setLevel(logging.INFO)
logger.info(
f"Running partition node to extract content from json files. "
f"Config: {partition_config.to_json()}, "
)
```
Now replace the first cell with the following and rerun the Python code.
Only the masked logging output should remain.
```
!git clone https://github.com/Unstructured-IO/unstructured.git && cd unstructured && git checkout fix/rm-log-dupes && pip install -e .
```
