I'd really like this idea, async call will definitely improve overall performance for cloud control system. In nova (and other components) there are some slow tasks which handle resource with long time running, which makes new tasks get a huge delay before getting served, especially for the high c

Why not change other services instead of glance? I see one reason is "glance is the only one service use this option name", but to me one reason to keep it as-it in glance is that original name makes more sense due to the option already under "profiler" group, adding "profiler" prefix to it is real
