William Dauchy da3b466fc2 MEDIUM: stats: allow to select one field in stats_fill_be_stats
prometheus approach requires to output all values for a given metric
name; meaning we iterate through all metrics, and then iterate in the
inner loop on all objects for this metric.
In order to allow more code reuse, adapt the stats API to be able to
select one field or fill them all otherwise.
This patch follows what has already been done on frontend side.
From this patch it should be possible to remove most of the duplicate
code on prometheuse side for the backend

A few things to note though:
- status and uweight field requires prior compute, so I moved that to a
  sort of helper `stats_fill_be_stats_computesrv`.
- all ST_F*TIME fields requires some minor compute, so I moved it at te
  beginning of the function under a condition.
