#8864: DriveSetup should recognize SSD's.

SSD's have an internal 4K block size.
But DriveSetup always 'recommends' the user initialize the Partition with
2K blocks.
This block size mismatch results in poorer performance and faster wear on
SSD drives.
E.g.: two 4K blocks get used when attempting to write a total of 4K worth
of data to the device. (eg: 1 4K block used for the first 2K write. It is
then discarded and another 4K block used for the second 2K write).
DriveSetup should check if the drive is an SSD and make adjustments to its
'recommended' block size for the partition.
Also, it should attempt to enforce a policy of aligning the partition to a
4K boundary when the drive is an SSD.
