Enhancements
* **Change Confluence Source Connector authentication parameters to support password, api token, pat token and cloud authentication**
Fixes
* **Fix SQL uploader stager** - When passed `output_filename` without a suffix it resulted in unsupported file format error. Now, it will take a suffix of `elements_filepath` and append it to `output_filename`.
* **Fix Snowflake uploader** - Unexpected `columns` argument was passed to `_fit_to_schema` method inside SnowflakeUploader `upload_dataframe` method.
