New Persistent Disk performance model

Raise the overall caps: The highest performing volumes now have the following limits

2000 random read IOPS (up from 250)
2400 random write IOPS (up from 600)
180 MB/s of streaming reads (up from 120 MB/s)
120 MB/s of streaming writes (same as previous limit)

Simplify scaling of IO: As we’ve publicly discussed, PD volumes are striped across hundreds or even thousands of physical devices. With PD, we manage the RAID for you so you never have to stripe multiple small volumes together inside a VM to increase IO. You get the same performance for a single 1 TB volume as for 10 x 100 GB volumes
