remove dict forwarding
  add api retries on NotMaster
  


ndb/include/kernel/signaldata/AlterIndx.hpp:
  Add NotMaster error code
ndb/include/kernel/signaldata/BuildIndx.hpp:
  Add NotMaster error code
ndb/include/kernel/signaldata/CreateIndx.hpp:
  Add NotMaster error code
ndb/include/kernel/signaldata/CreateTrig.hpp:
  Add NotMaster error code
ndb/include/kernel/signaldata/DropIndx.hpp:
  Add NotMaster error code
ndb/src/kernel/blocks/dbdict/Dbdict.cpp:
  Never forward requests,
    instead REF to API who will retry towards correct node
ndb/src/ndbapi/NdbDictionaryImpl.cpp:
  1) Set error code for timeout
  2) Handle NotMaster with retry in all DICT requests
ndb/src/ndbapi/ndb_cluster_connection.cpp:
  Fix so that input values is in seconds and not 100ms's
sql/ha_ndbcluster.cc:
  Wait 3 sec for all nodes to connect...
