Comment 7 for bug 1260193

Since all wsrep-provider-options are logged to error log as:

131230 21:10:54 [Note] WSREP: Passing config to GCS: base_host = 127.0.0.1; base_port = 4567; cert.log_conflicts = no; gcache.dir = /pxc/datadir/; gcache.keep_pages_size = 0; gcache.mem_size = 0; gcache.name = /pxc/datadir//galera.cache; gcache.page_size = 128M; gcache.size = 128M; gcs.fc_debug = 0; gcs.fc_factor = 1; gcs.fc_limit = 16; gcs.fc_master_slave = NO; gcs.max_packet_size = 64500; gcs.max_throttle = 0.25; gcs.recv_q_hard_limit = 9223372036854775807; gcs.recv_q_soft_limit = 0.25; gcs.sync_donor = NO; gmcast.listen_addr = tcp://127.0.0.1:4010; replicator.causal_read_timeout = PT30S; replicator.commit_order = 3

I think it should be fine to show only the options explicitly set
(either at startup or runtime).
