- Change the current logic in mtr.pl which detects and enables testing
   of ndbcluster to automatically turn on testing of the 'ndbcluster'
   suite when it's been detected that
  1) This is MySQL Server(no ndb-Y.Y.Y in version)
  2) ndbcluster is supported(i.e MySQL Server compiled with NDB).
  3) Full ndbcluster testing has not been requested(with --ndb|--include-ndbcluster)
  4) ndbcluster has not been skipped(with --skip-ndb[cluster])

 - Add the new 'ndbcluster' suite and implement basic.test

 - Intention of the 'ndbcluster' suite is the perform basic integration check
   of MySQL Server compiled with NDB.

 Example test of MySQL Server with NDB:
  $bld_trunk_with_ndb> cmake ../trunk -DWITH_NDBCLUSTER_STORAGE_ENGINE=1
  $bld_trunk_with_ndb> make
  $bld_trunk_with_ndb/mysql-test> ./mtr
   <snip>
  Checking supported features...
  - enabling ndbcluster(for integration checks)
  <snip>
  ndbcluster.basic                            [ pass ]
  <snip>

  Alternatively:

  $bld_trunk_with_ndb/mysql-test> ./mtr basic
  $bld_trunk_with_ndb/mysql-test> ./mtr ndbcluster.basic
  $bld_trunk_with_ndb/mysql-test> ./mtr --ndb
   ^run all ndb* suites in addition to the new 'ndbcluster'
