Azure was the only user of `DiskByIDDir` and since we're using the different approach to get the device details for azure instances, this code is not required anymore. Signed-off-by: Jeremi Piotrowski <jpiotrowski@microsoft.com>

support Azure generation 2 VMs
Azure generation 2 VMs present the configuration DVD in a slightly different way so ignition needed adaptation. The provisioning contract is documented here https://docs.microsoft.com/en-us/azure/virtual-machines/linux/provisioning. After this change ignition scans all block devices that match the configuration DVD filesystem and searches for the provisioning data.
This is a backport of this upstream PR coreos/ignition#1241.
How to use
Testing done
Checked that VM boots and hostname + ssh_authorized_keys gets populated. Kola to follow to verify that nothing breaks.
