Support customizing namespace when used as subchart #239
Description
Is your feature request related to a problem ?
When a chart is used in an umbrella chart as a subchart, its resources are deployed into the same namespace specified when the umbrella chart was deployed. Sometimes this is undesirable because you want to be able to deploy subchart resources into a different namespace.
Describe the solution you'd like.
This is a known issue in the Helm community and some open source projects have adopted a convention to solve it where a namespace (sometimes called something different - it's up to the chart authors) value is added to the chart and referenced throughout the chart for each resource.
You can see an example of this approach in the cert-manager project.
Can support for this be added to the Flux CD chart?
Describe alternatives you've considered.
Installing the Flux CD chart first, into whichever namespace I want to, and then deploying my umbrella chart next, with its resources referencing the Flux CD resources deployed by the Flux CD chart. An issue with this approach is that users of my umbrella chart can't deploy it this way with a single helm install command. It's broken up into multiple commands that must be orchestrated.
