PM-2742 changes the default of the allowDiskUse per-query parameter and introduces allowDiskUseByDefault per-node parameter. In this context, we might need to adjust the statistics.

• SERVER-64184 added tracking the explicit use of allowDiskUse:true per-query parameter
• Do we want to continue tracking the explicit use of allowDiskUse:true pas PM-2742? (true will be the new default)
• Do we want to track the usage with find command as well?
• Do we want to track the explicit use allowDiskUse:false?
• Do we want to track both explicit and implicit use?
• Do we want to track changes of the allowDiskUseByDefault parameter?
