zhanggang 86497c3e69 Wrong load removed node of galera cluster.

trove/common/strategies/cluster/experimental/galera_common/api.py.
Method "shrink" in class GaleraCommonCluster,when use DBInstance.find_all
should set argument deleted=False, otherwise it may missing raise a
ClusterShrinkMustNotLeaveClusterEmpty exception.
Same problem at galera_common/taskmanager.py. Method "shrink_cluster" in
GaleraCommonClusterTasks, call DBInstance.findall() with deleted=False
to exclude deleted nodes and that can avoid a NotFound error.
