Override namespace through values.yaml

[morozovcookie]

Hello! I would like to purpose to add possibility to override namespace via values.yaml. Especially for the k8s-stack chart.

In my case I have a single chart where I have all I need as dependencies. By default Helm Chart will be installed into {{ .Release.Namespace }}, but I need to control this behavior. I want to setup any dependencies in the separate namespaces.

Similar feature exists in the kube-prometheus-stack.
