- noplog driver pkg for '--log-driver=none' (null object pattern)
- centralized factory for log drivers (instead of case/switch)
- logging drivers registers themselves to factory upon import
(easy plug/unplug of drivers in daemon/logdrivers.go)
- daemon now doesn't start with an invalid log driver
- Name() method of loggers is actually now their cli names (made it useful)
- generalized Read() logic, made it unsupported except json-file (preserves
existing behavior)
Spotted some duplication code around processing of legacy json-file
format, didn't touch that and refactored in both places.
