export PPML model for guest-single-y case

[majorinche]

can we support export PPML model for guest-single-y hetero FML case

(i.e., guest only provides Y label, and host provides all X features)

then we can export only host models to do predict business.

thanks majorin

PPML or PMML? please give the supported model list of hero FML, then we can evaluate.
