What this PR does / why we need it: ADOPTERS list is getting out of hand We have kubevirt/kubevirt:ADOPTERS.md, kubevirt/kubevirt:~/_data/adopters.yml, Karena's doc with a list of adopters. We also have adopters scattered throughout the project via mailing list subscription, slack membership, pull req creation, YouTube video publishing, Blog publishing.

Let's start to get a handle on this and consolidate all adopters to kubevirt/kubevirt:ADOPTERS.md... See kubevirt/kubevirt/pull/6385. Then we can use adopters.py to populate a yaml file that the jekyll engine can use to build the index.html file for the website.

Note: https://github.com/kubevirt/kubevirt/pull/6385 should be merged before this merges

The script works 100% as is. We can manually update adopters.yml manually since we have a lot of eyes on kubevirt/kubevirt ADOPTERS right now.

We will address automation in a future pull req.

I'm removing the hold tag so that we can rebase/merge when the link gets fixed via the istio pull.
