Update auth libraries, fix brandingSettings update
Browse files Browse the repository at this point in the history 
The oauth2client library is deprecated. This update changes the sample to use the google-auth and google-auth-oauthlib libraries instead. Update code sample to update brandingSettings (defaultLanguage) and localizations separately. Support localized channel title and localized channel description.
