* Add cert-manager integration doc
This starts the new "Integrations" page, which will include many other
integrations in the future. For now, I have added cert-manager
integration. We have an existing doc for this at
https://istio.io/docs/tasks/traffic-management/ingress/ingress-certmgr/
which I think we can remove, but I did not do that in this PR.
Note to the reviewer: this is explicitly not a task, as we do not
control cert-manager. Having an explicit set of steps and verifications
requires an exact working directions, which is maintained as
cert-manager evolves, etc. The goal here was to link out to cert-manager
docs wherever possible, and just document the very minimal amount needed
to actually get things integrated with Istio. As you can see from the
doc this is fairly minimal - for the most part, its just referencing a
secret crated by cert-manager.
