Not great to tell users to use single dashes only to print a warning that they shouldn't do that. :-) Signed-off-by: Matt Lord <mattalord@gmail.com>

Description
The legacy sharding code — e.g.
SplitClone— has long since been replaced by VReplication based workflows likeMoveTables.This PR ensures that all related user commands are clearly marked as deprecated so that all related code can be removed in v15.
