Description:
with the fix to allow ndb_mgmd processes to be stopped and restarted, ALL STOP changed to stop all MGMD nodes as well. This is undesired behaviour as SHUTDOWN exists for this purpose.

ALL STOP (stop all DB nodes)
SHUTDOWN (stop everything)

There's also a race condition where shutting down mgm servers could have an error when there was none.

How to repeat:
ALL STOP

Suggested fix:
change to intended behaviour.

TODO (from review by tomas):
1. extend mgm api protocol to signal disconnect on return
2. CommandInterpreter down _nothing_, just forwards the node id's... and disconnects if signelled
3. extend mgmapi to have calls for shutdown DB only or shutdown ALL.
4. Services.cpp _only_ relays nodeids, receives stopSelf, and reports disconnect if need be
5. MgmtSrvr.cpp does all the sorting/stopping and returns stopSelf...

 possibly a ndb_mgm_shutdown() that accepts a node type parameter.
