The script generates a csv file by reading a yaml file
which contains the list of translators (e.g., translation_team.yaml)
with user name and e-mail addresses by interacting with Zanata API.
The script utilizes ZanataUtils in openstack-infra/project-config
to read zanata.ini configuration file which contains Zanata API key.
Note that the Zanata API key is required to use Zanata accounts API.
