Will download all CSAF documents for the given domains, by trying each as a CSAF provider.
If a domain starts with https:// it is instead considered a direct URL to the provider-metadata.json and downloading procedes from there.
Increasing the number of workers opens more connections to the web servers to download more advisories at once. This may improve the overall speed of the download. However, since this also increases the load on the servers, their administrators could have taken countermeasures to limit this.
