ISSUE:       2644
TITLE:       Nbackup as online dump
DESCRIPTION:
  We create table and leave it empty, than we run "nbackup -b 0 <source_db> <nbk_level_0>".
  After this add one row in the table in source DB.
  Then we obtain database GUID of sourec DB and use it in following commands:
    1. nbackup -b <GUID> <source_db> <addi_file>
    2. nbackup -i -r <nbk_level_0> <addi_file>
  Finally, we:
    1. Check that inserted record actually does exist in <nbk_level_0>;
    2. Run online validation of <nbk_level_0> - it sould NOT produce any errors.
