Observed generation field addition in solr-operator code

Hi,
I am running solr operator 0.6.0 and solr version 9.1.0 in kubernetes environment and I want to configure the below changes:
I want to add a status field called observed generation in solr-operator code, this field will help me to check how many times changes were made in solr were successful.
Whenever we are describing the CustomResource deployed for a Solr cluster we should be able to display current status of cluster deployment such as Pending, Running or Failed. I want to see this is under status section while describing CustomResource. Also I want observed generation field to be increase with every successful solr deployment.
So let me know where exactly I need to add this feature in solr operator code.

No file or test is named in the issue. Start by locating the Solr CustomResource definition and the controller reconciliation entry point, then trace how deployment success and status are recorded. Done means the CustomResource status exposes deployment state and an observed generation that updates after successful deployments.
