Fix namespace templating inconsistencies (#713)

### Description of the change

Added namespaces to all the template files to better support alternate templaters in gitops systems

### Benefits

Gitops system that have different ways of handling helm templates can actually deploy this chart correct, especially through subcharts

### Possible drawbacks

Potential regression when upgrading, though this should be unlikely per @jessesanford 's comments with it defaulting back to the existing behaviour
