[Qemu-devel] [PATCH v7 4/5] qemu-iotests: Allow caller to disable underscore convertion for qmp

[Fam Zheng <famz@redhat.com>]

QMP command "block_set_io_throttle" expects underscores in parameters
instead of dashes: {iops,bps}_{rd,wr,max}.

Add optional argument conv_keys (defaults to True, backward compatible),
it will be used in IO throttling test case.
