O-Subject: [RHEL-7 qemu-kvm PATCH 09/18] blockjob: rename BlockJobType to BlockJobDriver
Bugzilla: 1041301

We will use BlockJobType as the enum type name of block jobs in QAPI,
rename current BlockJobType to BlockJobDriver, which will eventually
become a set of operations, similar to block drivers.
