#184 Jobchain step parameters with agent

[Emmanuel Averty]

I want to execute a job chain threw an agent.
The job chain steps have parameters. When I create an order on the host where jobscheduler is running (no agent), I can see the value of these step parameters. But when I configure the job chain process class to use my agent, the environment variables corresponding to my step parameters are empty.

In test.zip, you can found a example.

Order output when NO process class is used (seems correct to me):

In this log : there's no output after «## Jobchain step value :»
«oon» is the hostname where the agent runs. It's a lxd container.
