test: add image streaming tests
This patch adds a test suite for the image streaming feature. It exercises the 'block_stream', 'block_job_cancel', 'block_job_set_speed', and 'query-block-jobs' QMP commands. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
