[0kashi]

Integrate with Azure ARC for enabling Azure Monitor and Log Analytics

[konghot]

Azure ARC already supports Openshift clusters, and hence it supports ARO clusters: https://learn.microsoft.com/en-us/azure/azure-arc/kubernetes/validation-program https://learn.microsoft.com/en-us/azure/azure-arc/kubernetes/quickstart-connect-cluster?tabs=azure-cli%2Cazure-cloud

This item is about further improvements to the integration so that additional features can be enabled for ARO clusters (specific to ARO, over and above regular Openshift).
