Create a new variable called galera_cluster_members which is a list of the hosts that make up the galera cluster. Set the default value to groups['galera_all'] which is the group used by openstack-ansible to refer to the members of the cluster. Replace all other references to groups['galera_all'] with the new variable. This allows other consumers of this role to use their own group naming scheme. Add a new task to verify that current host is a member of galera_cluster_members. Add the var galera_client_drop_config_file=true to the role dependency galera_client, this is required because the default value for that var in the galera_client role is based on membership of the galera_all group. Modify the functional testing to override galera_cluster_members, this aims to prevent the return of any hard-coded role references. Change-Id: I59af07217114a001cbebaa95a651919d53c9ec21
