with Maintenance Mode (KVM)

   My 2 cents - adding forceMaintenance is really going to complicate code 
unnecessarily. Marking host to maintenance and migration jobs for VMs are 
separate background tasks. Putting a host into maintenance is not going to be a 
frequent operation inmho worth the code complexity.
   
   Perhaps sticking to the general theory - `If Migrations cannot be completed 
and host cannot be put to maintenance safely, we put the host to 
ErrorInMaintenance state`. At the same time we log/throw exception for 
informing the admins.
   
   Admins can put the VMs off or snapshot or whatever works best - then they 
can manually shutdown all VMs on a host as needed and retry maintenance 
transition.
