XML: remove notion of arbitrary/relative dimensions
Currently in v2.0 branch, the room dimensions are relatives and arbitrary, w/o notion of physical unit.
This is not really easy to perceive from user standpoint, so this should be fixed and replaced by either units in the metric system or number of racks.
This issue concerns Slurm-web v2 which is not maintained anymore. You are highly encouraged to test the new version v3.0.0 for which the quick start guide is available online: https://docs.rackslab.io/slurm-web/install/quickstart.html
Unless someone is motivated to maintain the old version of Slurm-web or you have a justified reason to keep this issue open, it will be closed in a few weeks.
For the reasons explained in the previous comment, I finally close this issue.
