[c-nsp] ASR 9000 Upgrade Expectations

[Jared Mauch]

We see around 1 hour of traffic loss due to upgrade times before adding in FPD and others, which can extend to more like 3 hours. 

There were improvements that went in 533+ which should improve your experience. I haven't checked if 602 hit CCO but you may want to look at that, or wait for 534.
