Cleaning before MR

@kristin Changed the part of code that contains "ATH_MSG_" ERROR -> WARNING FAILURE -> SUCCESS. (this is to avoid throwing a fatal error when AFP containers are not available)

And added few histograms.

This merge request affects 1 package:

• ForwardDetectors/AFP/Run3AFPMonitoring

Adding @ggach as watcher

added ForwardDetectors master review-pending-level-1 labels

Changes look fine and are unrelated to the known failure. To note, it says in the description that you added histograms, but you only seemed to change the white space. Was this forgotten? If so, it can be added in another MR. Approving. Clara (L1)
