We need to add  next rules to planner

In order to be able to make this transformation for the query:
{noformat}
"select name from (\n"
        + "  select *\n"
        + "  from dept\n"
        + "  where deptno = 10)\n"
        + "where deptno = 10\n"

BEFORE=
LogicalProject(NAME=[$1])
  LogicalFilter(condition=[=(CAST($0):INTEGER, 10)])
    LogicalProject(DEPTNO=[$0], NAME=[$1])
      LogicalFilter(condition=[=(CAST($0):INTEGER, 10)])
        IgniteTableScan(table=[[PUBLIC, DEPT]])

AFTER=
IgniteProject(NAME=[$1])
  IgniteProject(DEPTNO=[$0], NAME=[$1])
    IgniteFilter(condition=[=(CAST($0):INTEGER, 10)])
      IgniteTableScan(table=[[PUBLIC, DEPT]])
{noformat}
