 * This enum defines Livy's API versions.

 * Version is defined as ..
 * When making backward compatible change (adding methods/fields), bump minor version.
 * When making backward incompatible change (renaming/removing methods/fields), bump major version.
 * This ensures our users can safely migrate to a newer API version if major version is unchanged.
