Third stage:
- Cdist calls the "gencode" binary of the providers
for every created object. This binary should create
code to be executed on the target on stdout.
If the gencode binary fails, it must print diagnostic
messages on stderr and exit non-zero.

Scope of code execution on the client
It should be assumed that the clients are pretty dumb
and thus do not have high level tools like python
