Update auth libraries, add snippet metadata opts
The oauth2client library is deprecated. This update changes the sample to use the google-auth and google-auth-oauthlib libraries instead. In addition, the code now supports other arguments for updating snippet metadata (title, description, tags). The --tags argument replaces the existing tags, while the --add_tag argument appends a tag to the current list.
