use max_workers from datacenter.cfg for stopall/migrateall

Browse Source 
If set limit the maximal worker count to the new datacenter.cfg
setting 'max_workers'.

For stopall we prefer this over the cpu count if it's set.

For migrateall we prefer the parameter but allow now to ommit
the parameter and then we use the new setting if set.
if both are not set we throw an error.
