Remove old Broadwell nodes from inventory

[mira-miracoli]

The non-high-mem and non-gpu Intel Broadwell nodes are decommissioned now.
(we can also fully remove the flavor soon – it will be in git still)

[bgruening]

Those are already gone, correct? So merging will not change anything or reduce the amount?

[mira-miracoli]

Yes, the c36 vm's are gone, except for those with large memory or GPUs but they are not rewired yet.
condor_status -compact | grep c36
should not show anything
the same for c28m225
