make helper methods available in variables files

[tongueroo]

This is a 🐞 bug fix.
This is a 🙋‍♂️ feature or enhancement.

• I've added tests (if it's a bug, feature or enhancement)
• I've adjusted the documentation (if it's a feature or enhancement)
• The test suite passes (run bundle exec rspec to verify this)

Summary

Load custom variables last so helpers are available in variables files https://kubes.guru/docs/variables/basic/

Context

Would be nice to be able to access helpers like google_secret in variables files and keep templates simpler with only variables.

How to Test

.kubes/variables/dev.rb

@cert = google_secret("cert-demo-global", base64: false)

.kubes/resources/web/ingress.yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: web
  annotations:
    ingress.gcp.kubernetes.io/pre-shared-cert: '<%= @cert %>'
spec:
  defaultBackend:
    service:
      name: web
      port:
        number: 80
