feature request - support iSCSI check-in/out drivers

[richhartdr]

Another feature request: Support iSCSI check-in/out drivers so multiple backup servers can use the same tape library... The IBM drivers I use DO support this, but Veeam does not, this would be great for people migrating from something else and allowing them to setup/test the Veeam environment prior to complete cut over....and also allows people to continue to use both simultaneously if required due to any limitations...
