* An EPP flow that cancels a pending transfer on a {@link DomainResource}.

* @error {@link google.registry.flows.domain.DomainFlowUtils.NotAuthorizedForTldException}
* <p>The "gaining" registrar requests a transfer from the "losing" (aka current) registrar. The
* losing registrar has a "transfer" time period to respond (by default five days) after which the
* transfer is automatically approved. Within that window, this flow allows the gaining client to
* withdraw the transfer request.
*
* <p>When the transfer was requested, poll messages and billing events were saved to Datastore with
* timestamps such that they only would become active when the transfer period passed. In this flow,
* those speculative objects are deleted.
