♻️(dimail) refacto setup_dimail_db to call dimail client

Management command "setup_dimail_db" called dimail directly, thus
creating duplicated code. It now calls "create_domain" and "create_allow"
methods from DimailAPIClient (create_user is left unchanged to create
special users such as dimail admin or people)
