Michal Privoznik 687730540e virstoragefile: Introduce virStoragePRDef 
This is a definition that holds information on SCSI persistent
reservation settings. The XML part looks like this:

  <reservations enabled='yes' managed='no'>
    <source type='unix' path='/path/to/qemu-pr-helper.sock' mode='client'/>
  </reservations>

If @managed is set to 'yes' then the <source/> is not parsed.
This design was agreed on here:
