[toulouse][montcalm] Update montcalm with g5k-checks informations

Related to the Toulouse project.

Since Montcalm can now be deployed with kadeploy, I have gathered the cluster's properties via g5k-checks and put them in this Merge Request.

We have discovered that disks models are not homogene on the cluster. I had to add homogeneity exceptions to handle this problem for the moment, before trying to replace the missing disks with HPe.
