Add option to ignore thinktime for rated IO
By default, fio will ignore thinktime when calculating the next time to issue and IO, if rated IO is specified. This leads to fio entering a catch-up type of mode after doing the specified sleep. For some workloads, that may not be useful. If someone asks for a specific amount of IOPS and sets a thinktime, they may want to exclude the sleep time.
