Allow securityContext configuration on `kube-rbac-proxy` container

For [this](https://github.com/datainfrahq/druid-operator/blob/master/chart/templates/deployment.yaml#L68) specific part of the template that is for the `kube-rbac-proxy` container, would it be possible to allow configuration like whats currently done for the `manager` container [here](https://github.com/datainfrahq/druid-operator/blob/master/chart/templates/deployment.yaml#L101)?

Thank you :-)
