If <code>true</code>, this parameter causes the modifications in this request and any pending modifications to be
applied, asynchronously and as soon as possible, regardless of the <code>PreferredMaintenanceWindow</code>
setting for the cluster.

If <code>false</code>, changes to the cluster are applied on the next maintenance reboot, or the next failure
reboot, whichever occurs first.

If you perform a <code>ModifyCacheCluster</code> before a pending modification is applied, the pending
modification is replaced by the newer modification.
