Add support to resize rootfs if using LVM (#721)
This patch adds support to resize a single partition of a VM if it's using an
LVM underneath. The patch detects if it's LVM if the given block device
is a device mapper by its name (e.g. `/dev/dm-1`) and if it has slave
devices under it on sysfs. After that syspath is updated to the real
block device and growpart will be called to resize it (and automatically
its Physical Volume).
The Volume Group will be updated automatically and a final call to
extend the rootfs to the remaining space available will be made.
Using the same growpart configuration, the user can specify only one
device to be resized when using LVM and growpart, otherwise cloud-init
won't know which one should be resized and will fail.
