Subject: DataSourceSmartOS: change default fs on ephemeral disk from ext3 to
ext4.
ext3 is not able to support file system sizes that are needed in Joyent's
cloud. For the default block size of 4k, the maximum filesystem size
for ext3 is 2^32 * 4096 = 16 TiB.
This changes the default file system type from ext3 to ext4.
LP: #1763511
