Alejandro González Hevia 9392838150 Standardized log messages accross the different storage drivers.
Now all of the storage drivers use the field "storage-driver" in their log
messages, which is set to name of the respective driver.
Storage drivers changed:
- Aufs
- Btrfs
- Devicemapper
- Overlay
- Overlay 2
- Zfs
