you get all CRDs.  CRDs are separated by release and by component type in the CRD directory.

Istio has strong integration with certmanager.  Some operators may want to keep their current certmanager
CRDs in place and not have Istio modify them. In this case, it is necessary to apply CRD files individually.

kubectl apply -k github.com/istio/installer/base
```

namespace "istio.io/rev=prod". The "prod" revision tag could point to "1-7-6" initially and then be changed to point to "1-8-1"
at some later point.

This allows operators to change which Istio control plane revision should handle injection for a namespace or set of namespaces
without manual relabeling of the "istio.io/rev" tag.
