Review comment:
So @jdeppe-pivotal brought this up in standup the other day. The
decision the team landed on was to make these choices about data types based on
our implementation (e.g. what makes sense with java data types in geode) and to
guard against data types that we don't support at the command level (send an
error back to any client trying to pass a datatype that we don't support
internally). I'll make sure that Hscan follows this convention. I'll also put
in a story to make sure that we're documenting differences between what data
types we accept and what native redis accepts.
