This tool is primarily for debugging and development but can be used an example
of how an operator could enqueue objects manually if a problem is discovered -
might be particularly useful if you need to hack a fix into the reconciler
and re-run it.

This script enqueues an object to be evaluated by the reconciler.
Arguments:
policy_index: the policy the object is currently stored in.

timestamp: the timestamp of the datafile/tombstone.
