This change is a precursor to switching the default Docker storage driver to overlay2. Previously, Kayobe's default configuration included a 'data' LVM volume group, with a 'docker-volumes' logical volume mounted at /var/lib/docker/volumes. Additionally, if the Docker devicemapper storage driver was used, the data volume group would contain the docker-thinpool and docker-thinpoolmeta volumes. This LVM setup was really included for devicemapper, and while in some cases it may be useful to have docker volumes as a separate logical volume, this doesn't really make sense as a default. Often in environments using other Docker storage drivers, the data volume group would be removed from configuration. This change modifies the default LVM configuration to only create a 'data' volume group if the Docker storage driver is devicemapper. Additionally, new flags are added to make this choice independent from the storage driver, to support cases where the data volume group is required without devicemapper.
