Rework Attestation section

[fitzthum]

We have a section about attestation on the website. Currently it just has an old clone of the docs from the Trustee repo. This isn't very use friendly. We should update it with a foolproof guide to using Trustee with CoCo.

We should probably pick just one installation method to feature here. I am thinking that we might want to show how to use the Trustee operator, but I'm not sure. Any ideas? @bpradipt @Xynnn007 @lmilleri

Yes. The page looks still abstract. Besides the operator things, It would make sense to write some quick starts for AS & KBS deployment and usage, probably after the EAR PR as it would somehow change the behavior of AS. Certainly I can help with this.

One note is that we currently have this page. We should keep this functionality available but I'm not sure how it will work with the operator.
