Record failed benchmark runs in the database

Atm, when a benchmark job failed, nothing will be uploaded to the database. However, this makes it difficult to differentiate between a failed benchmark run and no benchmark run because there are no record in both cases.

To fix this, we will need to keep that in a dedicate conclusion field. The metric can probably be set to empty (or 0). This approach will work with #6277 (comment) without any change on HUD

short-term, upload benchmark with no data but extra_Info with conclusion field
