Description

Directory and file count is included in the OM NumKeys metric. When a directory is deleted from OM, its subdirectories and files are not subtracted from the current key count held by the NumKeys metric. We can decrement this metric in the OMDirectoriesPurgeRequestWithFSO sent out by the leader's directory deleting service so that the metric is updated asynchronously on the leader and all followers.
