Expose reconcile status as metrics to allow monitoring

[mhoshi-vm]

Describe the problem/challenge you have
One thing we need is at least be able to expose the reconcile status to an external monitoring sysytem. We have seen a cluster that was running fine for several days until we realized that it was actually failing to reconcile due to someone mistakenly changed the service account role.

This cannot be identified until somebody executes kubectl get apps

Describe the solution you'd like
Something like kubernetes_apps_reconcile_status metrics being exposed where 0 = success , 1 = fail , 2 = unknown then i think it's easy to monitor
