Register Assured Open Source Software to monitored indexes once available

Problem statement

See https://www.csoonline.com/article/3660799/google-to-launch-repository-service-with-security-tested-versions-of-open-source-software-packages.html

It would be great to allow users of Thoth to consume software packages from this repository. Let's register it to Thoth once it will be available. We can monitor all the releases (not only those that have been seen previously) as the index claims to be secured.
