Add silent option to forward to minijasminenode

[minijasminenode](https://github.com/juliemr/minijasminenode) already has support for disabling the terminal reporter: see it [here](https://github.com/juliemr/minijasminenode/pull/17).

I created a issue and proposed a [pull request](https://github.com/juliemr/minijasminenode/pull/25) for adding the same support for minijasminenode2. This adds the interface for forwarding the option to minijasminenode.

Consider it when support will be added in minijasminenode2.
