Add Python primitives generation

[Wyrdix]

The remote.py will probably need to be modified.

Hello,

what's the status of this one? Is it ready to be merged or you want to do the changes you speak about, on Remote.py, before merging? Do you want to adapt Python from in-JVM to remote after merging this, or you prefer to be able to test this code before any merge ?

In any case, many many thanks for your work, that's really appreciated.

Tough one, I guess it would be better to build upon this and go to a full python implementation before merge ? To be able to test it.

I am indeed a bit nervous about pushing code that is not tested at all. I think this was useful to reassess the overall design of the remote execution, as proved by your other PR that removes the need to duplicate things between remote languages. But I propose to NOT merge this one for now.

I would change my mind if not merging could create edit conflicts with future PRs and thus more work to keep this PR mergable. If this arises, I guess we could merge it right away even if the tests come in a few days/weeks only
