WL#2779 ndb_size.pl 

Add display of minimum requirements for various cluster parameters
e.g. DataMemory, IndexMemory, MaxNoOfTables, MaxNoOfAttributes etc

and the memory usage because of them.


ndb/tools/ndb_size.pl:
  Computer minimum parameter settings (MaxNoOfTables, Attributes, Indexes, Triggers) and the memory usage because of these settings.
ndb/tools/ndb_size.tmpl:
  display parameters
