Review Comment:
   They are currently marked as deleted and stay on storage as garbage, this 
was added to clean the garbage.

Review Comment:
   @slavkap I was under the impression that StorPool was a managed storage, but 
upon further inspection I found that it actually is not.  However,  this made 
me question, what does cloudstack consider a managed storage? Shouldn't 
StorPool/Linstor/SolidFire be considered managed storages for example?
   
   I've changed this so that the StorPool behavior stays the same.
