blockdev: add x-blockdev-set-iothread testing command
Currently there is no easy way for iotests to ensure that a BDS is bound
to a particular IOThread. Normally the virtio-blk device calls
blk_set_aio_context() when dataplane is enabled during guest driver
initialization. This never happens in iotests since -machine
accel=qtest means there is no guest activity (including device driver
initialization).
This patch adds a QMP command to explicitly assign IOThreads in test
cases. See qapi/block-core.json for a description of the command.
