NOT WORKING: Jaeger example deployment

[wisack]

This does not work. Persistent storage does not work applied via Helm chart and sometimes Kube-stack-prometheus, jaeger-collector and jaeger-query break as well. This is somehow PVC/StorageClass related and happened with cassandra deployment trying to allocate volume.
Things I've tried to make Jaeger persistent storage available:

• Badger
  No Helm chart support for Badger. Possible CRD deployment using kubectl or kubernetes-alpha-provider for Terraform is available, see: https://github.com/jaegertracing/jaeger-operator/blob/65490e8fdc240b3bf9a25297dfc1627372134791/examples/with-badger-and-volume.yaml

• Cassandra persistent storageClass: "azure-disk-retain" or different storageclass as well
  Does not bind to said storageClass and create PVC like it should ( see https://github.com/bitnami/charts/tree/master/bitnami/cassandra )

• Omitted the storageClass configuration so it uses default provisioner
  This works and it creates a new PVC, binds to it but its retain policy's not 'retain' so it deletes itself when pod drops.

Suggestions to continue development:

• kubectl deployment
• elasticsearch database

More info if deciding to go with cassandra deployment:

• schema.activeDeadlineSeconds: 750
  waits for 750seconds before applying cassandra indexing. If it's too low the database deployment isn't ready by the time
