Added support for verbose logging and csv-metadata to the prompt tune…

[nievespg1]

Description

The original prompt tuning client did not support metadata injection when creating the example code even when provided with a correct yaml config file.

In this PR I updated the prompt tuning client to support the default chunking strategy provided by the create_base_text_units workflow which injects any metadata into the text chunks as defined by the provided config file.

As a side note, I updated the logger logic to conform with the latest LoggerFactory paradigm and added verbose logging support.
