Akri Agent is not recreating instances upon configuration updates

[kate-goldenring]

Describe the bug
The latest changes to the agent exhibit different behavior than the previous (released) agent. If i install the debugEcho DH and discover two devices, two instances are created. Then if i update the installation to add brokerProperties, the instances should be recreated or at least updated to have the brokerProperty added now, but the new configuration state is not resolved.

To Reproduce
Install Akri dev with debug Echo DH and config:

helm install akri akri-helm-charts/akri-dev --set agent.allowDebugEcho=true     --set debugEcho.discovery.enabled=true     --set debugEcho.configuration.enabled=true     --set debugEcho.configuration.brokerPod.image.repository=nginx     --set debugEcho.configuration.brokerPod.image.tag=stable-alpine     --set debugEcho.configuration.shared=false

Result:

$ k get po,akrii,akric

Then upgrade installation with brokerProperty in config:

 helm upgrade --install akri akri-helm-charts/akri-dev --set agent.allowDebugEcho=true     --set debugEcho.discovery.enabled=true     --set debugEcho.configuration.enabled=true     --set debugEcho.configuration.brokerPod.image.repository=nginx     --set debugEcho.configuration.brokerPod.image.tag=stable-alpine     --set debugEcho.configuration.shared=false --set debugEcho.configuration.brokerProperties.random=value

The instances are not updated and broker pods not restarted:

$ k get akrii -o yaml | grep random
# no output
