Add support for $cmp in group or project aggregation [DATAMONGO-784]

[spring-projects-issues]

Vikas Garg opened DATAMONGO-784 and commented

Currently there is no support to have $cmp / $eq / $ne to be used in group or project aggregation. It would be a good to have feature. Also it would be helpful to improve on some of the documentation/examples for Criteria features

What about complex expressions (like $cmp, $cond) in the $sum operation?
The pull request seems to enhance projections only
