ccm zk集群扩容

以3节点集群扩容到7节点集群扩容为例，原zk server list由ceph1:2181,ceph2:2181,ceph3:2181扩容到ceph1:2181,ceph2:2181,ceph3:2181,ceph4:2181,ceph5:2181,ceph6:2181,ceph7:2181

1. 修改GlobalCache服务端/opt/gcache/conf/gcache.conf中zk_server_list

   1 2	[communicate] zk_server_list = ceph1:2181,ceph2:2181,ceph3:2181,ceph4:2181,ceph5:2181,ceph6:2181,ceph7:2181

2. 修改GlobalCache服务端和客户端/opt/gcache/conf/bcm.xml中对的ccm cluster下zk_server_list，参考验证Global Cache执行import导入最新ccm zk配置。
