cpu: Add request elasticity to the traffic generator
This patch adds an optional request elasticity to the traffic generator, effectievly compensating for it in the case of the linear and random generators, and adding it in the case of the trace generator. The accounting is left with the top-level traffic generator, and the individual generators do the necessary math as part of determining the next packet tick. Note that in the linear and random generators we have to compensate for the blocked time to not be elastic, i.e. without this patch the aforementioned generators will slow down in the case of back-pressure.
