[libvirt] [PATCH v2][TCK] add test case for block job lifecycle testing



v2: Add skip block for qemu only and 120s timeout for test

v1: Add tests for block job lifecyle and the test flow is as follows:
create 50M qed img with qed backing img->
block pull->abort block job->resume block pull->set block job speed->
wait to finish

+
+qemu/300-blockjob-lifecycle.t - verify the lifecycle of block job:
+block pull, set block job speed, get block job info and abort block job
+
+=head1 DESCRIPTION
+
+The test case validates that it is possible to block pull, set block job
+speed, get block job info and abort block job for domain using qed img
+with qed backing img
