Better performance with bursting enhancement on Azure Disks

We are excited to introduce the preview of bursting support on Azure Premium SSD Disks, and new disk sizes 4/8/16 GiB on both Premium & Standard SSDs. Eligible Premium SSD disks can now burst up to 30x of the provisioned performance target, providing better handling for spiky workloads. Posted at https://sl.advdat.com/2LYkU1a
