Removes the dependency of NDB_delete_all tool on NDBT library since this
should only be used for debugging purposes.

NDB_delete_all relies on NDBT library mainly for returning status codes
and printing them using 'NDBT_ProgramExit'. Besides that, it also uses
functionality for printing debug information and some utility methods.
However, NDBT library was built for testing purposes only and the
printed return information interferes with the testing tools.

Instead of relying on NDBT, new program return codes were defined
(NdbToolsProgramExitCodes.hpp) so they can be used for all NDB tools.
The current change also includes a small refactoring of restore tools which
had been decoupled from NDBT library and defined return codes internally,
in order to keep consistency.

NDB_delete_all also depends on some macros to log information. These
were also moved to another header file (NdbToolsLogging.hpp) so they can
be used in all NDB tools. Instead of resorting to g_err and g_info which
are specific of NDBT, ndberr and ndbout are now used.
