[Feature Request]: Add Mapping (sub-transformation) / Mapping (sub-pipeline)

[dsanderbi]

What would you like to happen?

I'd like to request the following step/transform that is present in PDI Mapping (sub-transformation) Currently only those are present in Apache HOP

We use "mapping (sub-transformation) in several of our projects since it supports more than one "Mapping input"

Further i should note that if the import tool is used to import transformations to Apache HOP all "Mapping (sub-transformations)" will be replaced by a "Simple-Mapping (sup-pipeline)". If more then one "Mapping input" is used on those you get a HopExeption:

To be able to import all our projects we would need the step "Mapping (sub-transformation)"
