Skip composeinfo-base.json creation if CTS is configured.
    
    If `cts_url` and `cts_keytab` is defined in the Pungi configuration,
    the `composeinfo-base.json` is not created and instead, the Pungi
    is used to generate this file and ODCS reads it in separate thread
    to get the `Compose.pungi_compose_id`.
