Setting Solver Verbosity

[jusevitch-mitll]

What's the best way to make the underlying SCIP instance verbose when using Ecole?

I tried adding the entry "display/verblevel": 4 to the scip_params dictionary when setting up a (Configuring) Ecole environment, but I'm not getting any display output when the SCIP solver is called.

In Ecole we call SCIPmessagehdlrSetQuiet, but I see no way to restore it through Ecole's Python interface or PySCIPOpt.

This would need to be added.
