- adding a transform for `sdk` logs that fetches a value from an enrichment table `sdk_map` populated by file `sdk_map.csv` and updates the fields using this value.
- adding some fields to ignore/except in `opensearch` logs sink
**Important Notes**
_Please ensure that the `sdk_map.csv` file is properly formatted and accessible at the specified path. The name of the file should also match the name of the table in config i.e `sdk_map`._

**1. Configuration Files**
