Adds boundary scenario tests for "Project limits" values
1) test_max_zone_name_length Get project's "max_zone_name" value and try to create a zones with the name lengths of: 1. "max_zone_name" --> Expected: PASS 2. "max_zone_name +1" --> Expected: FAILED 2) test_max_recordset_name_length Get project's "max_recordset_name_length" value and try to create a recordsets with the name lengths of: 1. "max_zone_name_length" --> Expected: PASS 2. "max_zone_name_length +1" --> Expected: FAILED Change-Id: I7e54759c50551fc09f468f874a16054c15316560
