 Description   

$bucketAuto is not being pushed down to SBE, as SBE only supports $group stages that can be evaluated by HashAggStage.

Supporting $bucketAuto will likely require a different SBE stage, that does not currently exist, that performs range-based rather than hash-based grouping in order to satisfy the $bucketAuto semantic.

 $bucketAuto pushdown to SBE has been disabled by https://jira.mongodb.org/browse/SERVER-60226
