What this PR does / why we need it:

• Allows ingress annotations to be templated
• Bumps Grafana version to 6.7.3

Use case:

Traefik requires the namespace to be included in the name of middleware that you want to associate with the ingress. For example if you had a middleware named the same as your chart:

ingress:
  enabled: true
  annotations:
    traefik.ingress.kubernetes.io/router.middlewares: '{{ include "mychart.namespace" . }}-{{ include "mychart.fullname" . }}@kubernetescrd'

Not sure why it's so flaky. Can't be my changes since ingress not enabled in any tests.
