[libvirt] [PATCH v2 2/2] bhyve: add volumes support

[Roman Bogorodskiy]

Update bhyveBuildDiskArgStr to support volumes:

 - Make virBhyveProcessBuildBhyveCmd and
   virBhyveProcessBuildLoadCmd take virConnectPtr as the
   first argument instead of bhyveConnPtr as virConnectPtr is
   needed for virDomainTranslateDiskSourcePool,
 - Add virDomainTranslateDiskSourcePool call to
   virBhyveProcessBuildBhyveCmd and
   virBhyveProcessBuildLoadCmd,
 - Allow disks of type VIR_STORAGE_TYPE_VOLUME
