Advanced configuration options for DataStax Studio

Advanced configuration options are not explicitly set in the configuration.yaml file.

DataStax recommends contacting the DataStax services team before adding advanced configuration options. For the properties in each section, the parent setting has zero spaces. Each child entry requires at least two spaces. Adhere to the YAML syntax and retain the spacing.
