* Improved configuration: config loaded from a Hazelcast XML config file. * Config loading similar to JGroups, e.g. "protocol" substituted into config file name. * Hazelcast instance no longer started unless the "alfresco.cluster.name" property is set. * Current default member discovery protocol is UDP/multicast, however this is because this is the default set up shipped with Hazelcast - this is likely to change to TCP. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@34266 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
