block: Add status callback to bdrv_amend_options()
Depending on the changed options and the image format, bdrv_amend_options() may take a significant amount of time. In these cases, a way to be informed about the operation's status is desirable. Since the operation is rather complex and may fundamentally change the image, implementing it as AIO or a coroutine does not seem feasible. On the other hand, implementing it as a block job would be significantly more difficult than a simple callback and would not add benefits other than progress report to the amending operation, because it should not actually be run as a block job at all. A callback may not be very pretty, but it's very easy to implement and perfectly fits its purpose here.
