 Description   

Column scan can get complicated with filters push down, optimized projections, etc. We should review explain output for plans with a column scan and augment both SBE part and possibly the QSN part with relevant, human-readable info.

Also change stage name from "COLUMN_SCAN" to lower case w/o underscores.
