// Creates a delegation set (a group of four name servers) that can be reused by
// multiple hosted zones that were created by the same Amazon Web Services account.
//
// You can also create a reusable delegation set that uses the four name servers
// that are associated with an existing hosted zone. Specify the hosted zone ID in
// the CreateReusableDelegationSet request.
//
// You can't associate a reusable delegation set with a private hosted zone.
//
// For information about using a reusable delegation set to configure white label
// name servers, see [Configuring White Label Name Servers].
//
// The process for migrating existing hosted zones to use a reusable delegation
// set is comparable to the process for configuring white label name servers. You
// need to perform the following steps:
//
//   - Create a reusable delegation set.
//
//   - Recreate hosted zones, and reduce the TTL to 60 seconds or less.
//
//   - Recreate resource record sets in the new hosted zones.
//
//   - Change the registrar's name servers to use the name servers for the new
//     hosted zones.
//
//   - Monitor traffic for the website or application.
//
//   - Change TTLs back to their original values.
//
// If you want to migrate existing hosted zones to use a reusable delegation set,
// the existing hosted zones can't use any of the name servers that are assigned to
// the reusable delegation set. If one or more hosted zones do use one or more name
// servers that are assigned to the reusable delegation set, you can do one of the
// following:
//
//   - For small numbers of hosted zones—up to a few hundred—it's relatively easy
//     to create reusable delegation sets until you get one that has four name servers
//     that don't overlap with any of the name servers in your hosted zones.
//
//   - For larger numbers of hosted zones, the easiest solution is to use more
//     than one reusable delegation set.
//
//   - For larger numbers of hosted zones, you can also migrate hosted zones that
//     have overlapping name servers to hosted zones that don't have overlapping name
//     servers, then migrate the hosted zones again to use the reusable delegation set.
//
