Document/setup use of prometheus with egeria container deployment in k8s (helm)

[planetf1]

Tools like prometheus are used extensively to understand how an application is behaving/performing in large scale environments

We already have many pieces to make this work for egeria

• Spring can be configured with the appropriate endpoints for prometheus

  • The RedHat UBI8 openjdk image that we use to run egeria exposes endpoints

  We should add documentation on what is already possible.

  In addition should consider

  • The kafka/zookeeper image currently used from bitnami (in our lab) may not be integrated. How could we do this? Can we add prometheus support if needed? Do we just offer an alternative config that uses an existing cloud messaging bus (we did this with the vdc chart, using IBM event streams as an option)
  • We may learn more about additional data egeria itself may need to provide
