Bug #20336 CLUSTERLOG commands have no effect

ndb/src/kernel/blocks/cmvmi/Cmvmi.cpp:
  Bug #20336 CLUSTERLOG commands have no effect
  - with signal sender the clock issuing the command and the revceiver of the events are not the same
ndb/src/mgmsrv/MgmtSrvr.cpp:
  Bug #20336 CLUSTERLOG commands have no effect
  - make sure to actually send the update to ndb nodes, and wait for the reply
ndb/src/mgmsrv/Services.cpp:
  Bug #20336 CLUSTERLOG commands have no effect
  - make sure to compute max every time for log level
