CRDs Only Installation

From reading the docs, the operator functions similar to strimzi's entityoperator. It expects to be installed as an operator for each kafka cluster.

In a cluster with multiple kafka clusters, we only need to install the CRDs once. Rather than rely on helm's behavior for CRDs, it would be great if the chart provides a crdsOnly option. Alternatively, the CRDs could be a separate chart.

If this idea resonates with you, I can open up a PR.

Upon installing the operator, I noticed the RBAC use ClusterRole and ClusterRoleBinding. Shouldn't this be Role and RoleBinding instead? The operator expects a single namespace, kafka cluster, and operator namespace. It doesn't make much sense for it to be at the Cluster level.
