Description of problem: IP reconciliation is a feature in the latest whereabouts, and due to reports, this feature should be backported all the way to 4.6.z. The feature is in the form of a cron job which reconciles the IP addresses.
Version-Release number of selected component (if applicable): 4.6-4.10
How reproducible: Specialized. Customers often experience this when nodes are rebooted, or pods are force deleted, and therefore CNI DEL calls aren't processed in their entirety by Whereabouts
Steps to Reproduce: (We will produce a procedure which produces orphaned IP addresses)
Actual results: IP addresses will remain stranded, and never utilized again.
Expected results: IP addresses that were stranded become available for use again.
Additional info: 4.10 has the reconciliation code but still requires a bug fix from upstream.
