add mesh.scale to the json file

[jermuzet]

The feature --cfpdes.mesh.scale=0.001 can only be done through the cfg options. This could be an option in the Meshes part of the .json file, where the .msh here the file that is used is defined :

"Meshes":
{
    "cfpdes":
    {
        "Import":
        {
             "filename":"$cfgdir/file.msh",
             "scale":"0.001"
        }
    }
},
