/**
 * Test for expiration configuration. Tested with REST (verifies JBPAPP-6928) and HotRod.
 * Memcached cache cannot be configured to use expiration, see https://bugzilla.redhat.com/show_bug.cgi?id=909177#c5 .
 * Tests when individual requests use expiration are also in client tests, here we're testing that they override the global
 * configuration.
