1. The cache is not persisted.
2. We use an LRU cache to avoid extra garbage collection work. This
   means that some entries may be recycled before a pod has been
   deleted.

    // the type of update (create, update, sync, kill)
    UpdateType kubetypes.SyncPodType
    // optional callback function when operation completes
    // this callback is not guaranteed to be completed since a pod worker may
    // drop update requests if it was fulfilling a previous request.  this is
    // only guaranteed to be invoked in response to a kill pod request which is
    // always delivered.
