ALF-12866: WebDAV in-memory locking: configuration

* 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.
