Is your feature request related to a problem?/Why is this needed
Currently, to enable the csi-snapshotter container in the controller Deployment, you must set .Values.externalSnapshotter.enabled=true. This also causes the CRDs and snapshot-controller to be installed. This causes a conflict if the underlying kubernetes distro also installs the CRDs and snapshot-controller

Describe the solution you'd like in detail
Either fully decouple the csi-snapshotter container from the installation of CRDs/snapshot-controller, or add an override value so this can be enabled without adding CRDs/snapshot-controller

Describe alternatives you've considered
See 2 options above.
