allow custom namespace

[NOBLES5E]

Currently helm install doppler-kubernetes-operator doppler/doppler-kubernetes-operator --namespace doppler-operator-system --create-namespace will fail

Hi @NOBLES5E,

What are you hoping to do with the --namespace doppler-operator-system flag? With the default parameters, the doppler-kubernetes-operator helm chart will create the dopper-operator-system namespace as part of the installation.
