bug#10358 - ndb

  Cluster failure with non started nodes can result in timedout transactions


ndb/src/mgmapi/mgmapi.cpp:
  Increase timeout for restarts
ndb/src/ndbapi/ClusterMgr.cpp:
  Report NFCOMPLETEREP if no alive node exists 
    (instead of no connected node exists)
ndb/src/ndbapi/ClusterMgr.hpp:
  Report NFCOMPLETEREP if no alive node exists 
    (instead of no connected node exists)
