Update logs don't depict the right workflow

[AmitKumarDas]

Problem Statement: Current code of Metac logs the extra update checks even if the object is not a candidate for update.

Solution: Change the log statements present in following blocks of code:

https://github.com/AmitKumarDas/metac/blob/master/controller/common/manage_attachments.go#L299-L352

e.g.

if oObj.GetDeletionTimestamp() != nil && !e.IsUpdateDuringPendingDelete() {
		glog.V(4).Infof(
			"%s: Can't update %s: Pending deletion", e, DescObjectAsKey(dObj),
		)
		return nil
	}

to

if oObj.GetDeletionTimestamp() != nil && !e.IsUpdateDuringPendingDelete() {
		glog.V(4).Infof(
			"%s: Not eligible for update %s: Pending deletion", e, DescObjectAsKey(dObj),
		)
		return nil
	}
