+ [Impact]
+ Users with NVMe disks.
+
+ [Test case]
+ - Install system with NVMe disks; expect to pick the boot device.
+ Install should complete succesfully.
+
+ [Regression Potential]
+ None, this only adds matching for NVMe devices; any such devices will now be
matched based on the partition numbers rather than risking to match a character
device for NVMe formatting. This does not match regular block devices and
partitions.

On Ubuntu 16.04, when installing Ubuntu to an nvme drive, Ubiquity fails
to install grub. In ubiquity/misc.py the function default_grub targets
/dev/nvme0 instead of /dev/nvme0n1, which is the real name of the
device.
For single drive scenarios, this can be fixed by filtering out nvme devices
from the regex line:
old:
target = re.sub(r'(/dev/(cciss|ida)/c[0-9]d[0-9]|/dev/[a-z]+).*',
r'\1', target)
fixed:
target = re.sub(r'(/dev/(cciss|ida)/c[0-9]d[0-9]|/dev/(?!nvme)[a-z]+).*',
r'\1', target)
