Adding walltime for multinode + keeping temporary folder activated with environement variable
bos #37471: fix compilation on Windows operating system. Note that SMESH_Gen::send_mesh current implementation is vetoed on windows OS (system call)
1- ex30_tepal.py - vetoe this test on Windows since 3D Mesher is not available GHS3DRPL - MeshGemsh
2- creating_parallel_mesh.py: on windows we build Python without tcl/tk thus tkinter module is missing - do not raise exception in that case
Tested OK on Windows
