[RFC PATCH] blk-throttle: add burst allowance.

Allows configuration additional bytes or ios before a throttle is triggered. This allows implementation of a bucket style rate-limit/throttle on a block device. Previously, bursting to a device was limited to allowance granted in a single throtl_slice (similar to a bucket with limit N and refill

Allows configuration additional bytes or ios before a throttle is triggered. Slice end is extended to cover expended allowance recovery time. Usage would be e.g. per device to allow users to take up to X bytes/ios at full speed, but be limited to Y bps/iops with sustained usage. Signed-off-by:
