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

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

### Description of the change
This adds a new values object `serviceAccount`, that allows creating a dedicated ServiceAccount with the Helm Release into the cluster. It supports all common options like labels, annotations, name override (or referring to an externally created ServiceAccount), auto-mount token, image pull secrets.
It supersedes the stale PR #357.
### Benefits
Users can deploy Gitea with more fine-tuned security settings.
### Applicable issues
- related to #448
### Additional information
I've bumped the helm-unittest plugin in the CI build, to be able to use the `exists` and `notExists` feature in the new tests.
