CRDs

The setup has been adjusted so that CRDs can be installed in a first step to ensure that all application deployments are possible. Especially for CRDs which are used by nearly all applications this is useful, e.g. the Prometheus stack.

In the directory cluster/flux is a file cluster-crds.yaml which starts the processing of the CRDs. The respective glue objects for Flux are defined in the directory cluster/crds. They point typically into cluster/apps so that the details of the CRD installation are close the the related application itself.
