BUG#12037 ndb_mgmd IP address do not show in other ndb_mgmd processes

Extend ApiVersionConf to include address.


ndb/include/kernel/signaldata/ApiVersion.hpp:
  Extend ApiVersionConf to include inet_addr. the address used for communication to this node.
ndb/src/kernel/blocks/qmgr/QmgrMain.cpp:
  include connect address in ApiVersionConf
ndb/src/mgmsrv/MgmtSrvr.cpp:
  ::status() now also returns char* address of the node.
  For API or MGM, this is in ApiVersionConf.
  For NDB, this is the standard get_connect_address.
  
  When sending ApiVersionReq, try to send to a STARTED node (as these have
  properly joined the cluster and know the connect addresses).
  
  If versionNode is called for getOwnNodeId()==nodeId, try to get the address
  via ApiVersionConf. If that fails, look it up in the configuration.
ndb/src/mgmsrv/MgmtSrvr.hpp:
  Add char **address to prototypes.
ndb/src/mgmsrv/Services.cpp:
  Get the connect address from mgmsrv.status()
