Summary

Analysis of scalability improvement using MPI3 new communications (e.g. collective neighbours communications) instead of point to point communications.

ticket: #2011

Preview

Plan outlined in ticket #2011 is OK. Most likely changes to the code will be limited to LBC/lib_mpp.F90. 
I'm happy to test the changes in MO operational configurations. May be worth considering implementation 
in which changing the number of halo points is easy.
