bot_scaling: Add fields to capture min and max for reporting.

Add min and max fields to RoboCrop action to capture for reporting
purposes.  We have ceiling and floor fields today but they are part of
input config.  Adding capture fields for output is more logical than
exporting the config for reporting, and potentially exhausting the
limits on output properties.
